■Characteristics
Note: 1. To meet UL listing requirements with the H7CX-A11@ models, an OMRON P2CF-11-@ or P3GA-11 Socket must be mounted on the
H7CX. Otherwise, H7CX-A11@ models are considered to meet UL508 recognition requirements.
2. The Y92S-29 Waterproof Packing and Y92F-30 Flush Mounting Adapter are necessary to ensure IP66, NEMA4, and UL Type 4X water-
proofing between the H7CX and installation panel.

(according to DIN43700).
Note: 1. The mounting panel thickness
should be 1 to 5 mm.
2. To allow easier operability, it is
recommended that Adapters are
mounted so that the gap between
sides with hooks is at least 15 mm
(i.e., so that the panel cutout interval
is at least 60 mm).
3. It is possible to mount counters
side by side, but only in the
direction without the hooks.
If they are mounted side-by-side,
water-resistant specifications
cannot be ensured.

Note: 1. Depending on the operating environment, the condition of
resin products may deteriorate, and may shrink or become
harder. Therefore, it is recommended that resin products
are replaced regularly.
2. The H7CX’s panel surface is water-resistive (conforming to
IP66) and so even if drops of water penetrate the gaps be-
tween the keys, there will be no adverse effect on internal
circuits. If, however, there is a possibility of oil being present
on the operator’s hands, use the Soft Cover. The Soft Cover
ensures protection equivalent to IP54 against oil. Do not,
however, use the H7CX in locations where it would come in
direct contact with oil.
When using the Y92S-29, the degree of protection for the H7CX's
panel surface conforms to NEMA4, UL Type 4X, and IP66. (Depend-
ing on the operating environment, the condition of the panel may
deteriorate, shrink, or become harder. Therefore, regular replace-
ment is recommended.)

Explanation of Functions
Input Mode (cntm) (Setting possible using DIP switch.)
Set increment mode (UP), decrement mode (DOWN), or one of the
increment/decrement modes (UP/DOWN A, UP/DOWN B, or UP/
DOWN C) as the input mode. Input modes other than UP or DOWN
modes cannot be set using the DIP switch and so use the operation
keys if other modes are required. (For details on the operation of the
input modes, refer to Input Modes and Present Value on page 23.)
Dual Count Calculating Mode (calm)
When using as a dual counter, select either ADD (addition) or SUB
(subtraction) as the calculation method for the dual count value. SUB
mode can be used only when K-2, D, L, or H is selected as the output
mode with 6-digit models.
ADD: Dual count value = CP1 PV + CP2 PV
SUB: Dual count value = CP1 PV − CP2 PV
Output Mode (outm) (Setting possible using DIP switch.)
Set the way that control output for the present value is output. The
possible settings are N, F, C, R, K-1, P, Q, A, K-2, D, L, and H. Output
modes other than N, F, C, or K-1 cannot be set using the DIP switch
and so use the operation keys if other modes are required. The out-
put modes that can be set vary with the model. (For details on the
operation of the output modes, refer to Input/Output Mode Settings
on page 24.)
One-shot Output Time (otim) (Setting possible using DIP
switch.)
Set the one-shot output time (0.01 to 99.99 s) for control output.
One-shot output can be used only when C, R, K-1, P, Q, A, or K-2 is
selected as the output mode. Output times other than 0.5 s or 0.05 s
cannot be set with the DIP switch and so use the operation keys if
other settings are required.
One-shot Output 2 Time (otm2) (Setting possible using
DIP switch.)
When using as a 2-stage counter or batch counter, set the one-shot
output time (0.01 to 99.99 s) for control output (OUT2). One-shot out-
put can be used only when C, R, K-1, P, Q, A, or K-2 is selected as
the output mode. Output times other than 0.5 s or 0.05 s cannot be
set with the DIP switch and so use the operation keys if other settings
are required.
One-shot Output 1 Time (otm1)
When using as a 2-stage counter, set the one-shot output time (0.01
to 99.99 s) for control output (OUT1). One-shot output can be used
only when D, L, or H is selected as the output mode. If the output
time is set to 0.00, hold is displayed, and outputs are held. HOLD
cannot be set when the output mode is K-2.
Counting Speed (cnts) (Setting possible using DIP
switch.)
Set the maximum counting speed (30 Hz/5 kHz) for CP1 and CP2
inputs together. If contacts are used for input signals, set the count-
ing speed to 30 Hz. Processing to eliminate chattering is performed
for this setting.
Reset Input Signal Width (iflt) (Setting possible using
DIP switch.)
Set the reset input signal width (20 ms/1 ms) for reset/reset 1 and
total reset/reset 2 inputs together. If contacts are used for input sig-
nals, set the counting speed to 20 ms. Processing to eliminate chat-
tering is performed for this setting.
Decimal Point Position (dp)
Decide the decimal point position for the present value, CP1/CP2
present values, set value (SV1, SV2), total count value, and dual
count set value.
Prescale Value (pscl)
Pulses input to the counter are converted according to the specified
prescale value. (Setting range: 0.001 to 99.999 for 6-digit models
and 0.001 to 9.999 for 4-digit models.)
Example: To display the feed distance for systems that output
25 pulses for a feed length of 0.5 m in the form @@.@@ m:
1. Set the decimal point position to 2 decimal places.
2. Set the prescale value to 0.02 (0.5÷25).
NPN/PNP Input Mode (imod)
Select either NPN input (no-voltage input) or PNP input (voltage
input) as the input format. The same setting is used for all external
inputs. For details on input connections, refer to Input Connections
on page 11.
Display Color (colr)
Set the color used for the present value.
Note: When using as a 2-stage counter, this is the status of output 2.
Output Allocation (otst)
When using H7CX-AU@ models as a 2-stage counter, the output can
be flexibly allocated to either stage 1 or 2.
Transistor output can be allocated to SV1 and contact output for SV2
or vice verse, as in the following table.

Key Protect Level (kypt)
Set the key protect level.
When the key-protect switch is set to ON, it is possible to prevent setting errors by prohibiting the use of certain operation keys by specifying the

Input Modes and Present Value
Note: 1. If the configuration selection is set to dual counter, CP1 and
CP2 input will operate in the same way as the count input
(CP1) of UP (increment) mode.
2. a must be greater than the minimum signal width and b
must be at least 1/2 the minimum signal width. If they are
less, a count error of ±1 may occur.
Minimum signal width:16.7 ms (when maximum counting
speed = 30 Hz)
100 µs (when maximum counting
speed = 5 kHz)
3. Counting starts when the CP1 is turned ON after turning ON
the power.

Input/Output Mode Settings
Operation for 1-stage models is the same as that for OUT2.
When using a 2-stage model as a 1-stage counter, total and preset
counter, or dual counter, OUT1 and OUT2 turn ON and OFF simulta-
neously.
Note: 1. The full scale (FS) for H7CX 4-digit models is 9999.
2. When the present value reaches 999999, it returns to 0.
3. Counting cannot be performed during reset/reset 1 input.
4. If reset/reset 1 is input while one-shot output is ON, one-shot output turns OFF.
5. If there is power failure while output is ON, output will turn ON again when the power supply has recovered. For one-shot output, output
will turn ON again for the duration of the output time setting once the power supply has recovered.
6. Do not use the counter function in applications where the count may be completed (again) while one-shot output is ON.

Total and Preset Counter Operation
The H7CX has a total counter, separate from the 1-stage preset counter, for counting the total accumulated value.
Batch Counter Operation
The H7CX has a batch counter, separate from the 1-stage preset counter, for counting the number of times the count has been completed.
Note: 1. The batch count value is held at 0 during batch counter reset input.
2. If the batch count set value is 0, batch count will be performed but there will be no batch output.
3. The batch count value returns to 0 when it reaches 999,999 (9,999 for 4-digit models).
4. Once batch input has been turned ON, it will return to the ON state after power interruptions.
5. If the batch count set value is changed from a value that is greater than the batch count value to one that is less, batch output will turn ON.
6. After batch output turns ON, the ON state will be held even if the batch count set value is changed to a value greater than the batch count
value.
•The total counter continues to count the
total accumulated value when the present
value is reset using reset/reset 1 input
(reset key).
•The total count value is reset when the
total reset/reset 2 input is turned ON. If the
reset key is pressed while the total count
value is displayed, the total count value is
reset. The present value is also reset at
this time.
•The counting range of the total counter is
−99,999 to 999,999 (−999 to 9,999). The
total count value returns to 0 when it
reaches the full scale limit.

Dual Counter Operation
Using the dual counter allows the count from 2 inputs to be added or subtracted and the result displayed. It is possible to specify a set value for
which output turns ON when the set value matches the added or subtracted result.
OUT1 and OUT2 turn ON and OFF simultaneously.
Note: 1. Counting is not possible for CP1 during reset 1 input. CP2 will not be affected. The dual count value will be calculated based on a CP1
present value of 0.
2. Counting is not possible for CP2 during reset 2 input. CP1 will not be affected. The dual count value will be calculated based on a CP2
present value of 0.
3. The counting range for the dual count value is −99,999 to 999,999 (0 to 9,999 for 4-digit models). The counting ranges for the CP1 present
value and CP2 present value are 0 to 999,999 (0 to 9,999 for 4-digit models). If a present value exceeds 999,999 (9,999 for 4-digit mod-
els), FFFFFF (FFFF for 4-digit models) will be displayed to indicate an overflow, and all counting will stop.
•The operation after count com-
pletion for the dual counter
value is determined by the out-
put mode.
•The CP1 present value is reset
when reset 1 input is turned
ON and the CP2 present value
is reset when reset 2 input is
turned ON.
•If the reset key is pressed while
the dual count value, CP1
present value, or CP2 present
value is displayed, all of the
present values are reset and
outputs turn OFF. At this time,
counting is not possible for

Explanation of Functions
Tachometer Output Mode (totm) (Setting possible using
DIP switch.)
Set the output method for control output based on the OUT1/OUT2
set value. Upper and lower limit (HI-LO), area (AREA), upper limit
(HI-HI), and lower limit (LO-LO) can be set. (For details on the opera-
tion of the output modes, refer to Output Mode Settings on page 35.)
Counting Speed (cnts) (Setting possible using DIP
switch.)
Set the maximum counting speed (30 Hz/10 kHz) for CP1 input. If
contacts are used for input signals, set the counting speed to 30 Hz.
Processing to eliminate chattering is performed for this setting.
Decimal Point Position (dp)
Decide the decimal point position for the measurement value, OUT1
set value, and OUT2 set value.
Prescale Value (pscl)
It is possible to display the rate of rotation or the speed of a device or
machine to which the H7CX is mounted by converting input pulses to
a desired unit. If this prescaling function is not used, the input fre-
quency (Hz) will be displayed.
The relationship between display and input is determined by the fol-
lowing equation. Set the prescale value according to the unit to be
displayed.
Displayed value = f × a
f: Input pulse frequency (number of pulses in 1 second)
a: Prescale value
1. Displaying Rotation Rate
N: Number of pulses per revolution
Example:In order to display the rate of rotation for a machine that
outputs 5 pulses per revolution in the form @@.@rpm:
1. Set the decimal point position to 1 decimal place.
2. Using the formula, set the prescale value to 1/N × 60 =
60/5 = 12.
2. Displaying Speed
N: Number of pulses per revolution
d: Diameter of rotating body (m)
πd: Circumference (m)
Average Processing (aug) (Setting possible using DIP
switch.)
Flickering display and output chattering can be prevented using aver-
age processing (simple averaging). Average processing can be set to
one of four levels: no average processing, 2 times (i.e., the average
of 2 measurement values), 4 times, or 8 times. The measurement
cycle will be equal to the sampling cycle (200 ms) multiplied by the
average processing setting (i.e., the number of times). Average pro-
cessing enables fluctuating input signals to be displayed stably. Set
the optimum number of times for the application.
Auto-zero Time (aut=)
It is possible to set the H7CX so that if there is no pulse for a certain
time the display is force-set to 0. This time is called the auto-zero
time.
Note: Set the auto-zero time to a time slightly longer than the estimat-
ed interval between input pulses and within the setting range
(0.1 to 99.9 s). It will not be possible to make accurate mea-
surements if the auto-zero time is set to a time shorter than the
input pulse cycle. Setting a time that is too long may also result
in problems, such as a time-lag between rotation stopping and
the alarm turning ON.
Startup Time (stmr)
In order to prevent undesired output resulting from unstable input
immediately after the power supply is turned ON, it is possible to pro-
hibit measurement for a set time (0.0 to 99.9 s), the startup time. It
can also be used to stop measurement and disable output until the
rotating body reaches the normal rate of rotation, after the power
supply to the H7CX and rotating body are turned ON at the same
time.
NPN/PNP Input Mode (imod)
Select either NPN input (no-voltage input) or PNP input (voltage
input) as the input format. The same setting is used for all external
inputs. For details on input connections, refer to Input Connections
on page 11.
Display Color (colr)
Set the color used for the measurement value.
Note: 1. If the tachometer output mode is set to AREA, however, the
measured value is displayed in red when control output 1 is
OFF and in green when control output 1 is ON.
2. If the tachometer output mode is set to AREA, however, the
measured value is displayed in green when control output 1
is OFF and in red when control output 1 is ON.

Output Allocation (otst)
When using H7CX-AU@ models as 2-stage counter, each output can
be flexibly allocated to either stage 1 or 2.

Key Protect Level (kypt)
Set the key protect level.
When the key-protect switch is set to ON, it is possible to prevent setting errors by prohibiting the use of certain operation keys by specifying the
key protect level (KP-1 to KP-5). The key protect indicator is lit while the key-protect switch is set to ON. Confirm the ON/OFF status of the key-
protect switch after the H7CX is mounted to the panel.
Note: Changing mode to configuration selection mode ( + 1 s min.) or function setting mode ( 3 s min.).

■Operation in Configuration Selection Mode
Select which H7CX configuration is used (i.e., 1-stage counter, 2-stage counter, total and preset counter, batch counter, dual counter, or tachom-
eter) in configuration selection mode. The H7CX is also equipped with a DIP switch monitor function, a convenient function that enables the settings
of the DIP switch pins to be confirmed using the front display.
Note: 1. When the mode is changed to configuration selection mode, the present value is reset, outputs turns OFF, and counting (measuring)
stops.
2. Setting changes made in configuration selection mode are enabled when the mode is changed to run mode. If the configuration is
changed, the set value (or set value 1 and set value 2), OUT1 set value or OUT2 set value are initialized.

■Characteristics
Note: 1. To meet UL listing requirements with the H7CX-R11@ models, an OMRON P2CF-11-@ or P3GA-11 Socket must be mounted on the H7CX. Otherwise,
H7CX-R11@ models are considered to meet UL508 recognition requirements.
2. The Y92S-29 Waterproof Packing and Y92F-30 Flush Mounting Adapter are necessary to ensure IP66, NEMA4, and UL Type 4X waterproofing between the
H7CX and installation panel.

■Explanation of Functions
Basic Functions
(setting is performed with DIP switch)
Counting Speed
Set the maximum counting speed (30 Hz/10 kHz) for input. If con-
tacts are used for input signals, set the counting speed to 30 Hz. Pro-
cessing to eliminate chattering is performed for this setting.
Output Mode
Set the output method for control output based on the comparison
value. Upper and lower limit (HI-LO), area (AREA), upper limit (HI),
and lower limit (LO) can be set. (For details on the operation of the
output modes, refer to Output Mode Settings on page 56.)
Average Processing
Flickering display and output chattering can be prevented using aver-
age processing (simple averaging). Average processing can be set to
one of four levels: no average processing, 2 times (i.e., the average
of 2 measurement values), 4 times, or 8 times. For 5 Hz or higher,
the measurement cycle will be equal to the sampling cycle (200 ms)
multiplied by the averaging setting (i.e., the number of times). For
less than 5 Hz, the frequency will be measured when the input pulse
comes. Average processing enables fluctuating input signals to be
displayed stably. Set the optimum number of times for the applica-
tion.
NPN/PNP Input Mode
Select either NPN input (no-voltage input) or PNP input (voltage
input) as the input format. When using a two-wire sensor, select NPN
input. The same setting is used for all external inputs. For details on
input connections, refer to Input Connections on page 47.
Advanced Functions
(setting is performed with operation keys)
Decimal Point Position (dp)
Decide the decimal point position for the measurement value and
comparison value.
Prescale Value (pscl)
It is possible to display the rate of rotation or the speed of a device or
machine to which the H7CX-R is mounted by converting input pulses
to a desired unit. If this prescaling function is not used, the input fre-
quency (Hz) will be displayed.
The relationship between display and input is determined by the fol-
lowing equation. Set the prescale value according to the unit to be
displayed.
Displayed value = f × a
f: Input pulse frequency (number of pulses in 1 second)
a: Prescale value
1. Displaying Rotation Rate
N: Number of pulses per revolution
Example:In order to display the rate of rotation for a machine that
outputs 5 pulses per revolution in the form @@.@rpm:
1. Set the decimal point position to 1 decimal place.
2. Using the formula, set the prescale value to 1/N × 60 =
60/5 = 12.
2. Displaying Speed
N: Number of pulses per revolution
d: Diameter of rotating body (m)
πd: Circumference (m)
Note: If the prescale value setting is incorrect, a counting error will oc-
cur. Check that the settings are correct before using this func-
tion.
Auto-zero Time (aut=)
It is possible to set the H7CX-R so that if there is no pulse for a cer-
tain time the display is force-set to 0. This time is called the auto-zero
time.
Note: Set the auto-zero time to a time slightly longer than the estimat-
ed interval between input pulses and within the setting range
(0.1 to 999.9 s). It will not be possible to make accurate mea-
surements if the auto-zero time is set to a time shorter than the
input pulse cycle. Setting a time that is too long may also result
in problems, such as a time-lag between rotation stopping and
the alarm turning ON.
Startup Time (stmr)
In order to prevent undesired output resulting from unstable input
immediately after the power supply is turned ON, it is possible to pro-
hibit measurement for a set time (0.0 to 99.9 s), the startup time. It
can also be used to stop measurement and disable output until the
rotating body reaches the normal rate of rotation, after the power
supply to the H7CX-R and rotating body are turned ON at the same
time.

Key Protect Level (kypt)
Set the key protect level.
When the key-protect switch is set to ON, it is possible to prevent setting errors by prohibiting the use of certain operation keys by specifying the
key protect level (KP-1 to KP-5). The key protect level is set in the function setting mode. The key protect indicator is lit while the key-protect
switch is set to ON. Confirm the ON/OFF status of the key-protect switch after the H7CX is mounted to the panel.

•Do not use the product in locations where condensation may occur
due to high humidity or where temperature changes are severe.
•Store at the specified temperature. If the H7CX has been stored at
a temperature of less than –10°C, allow the H7CX to stand at room
temperature for at least 3 hours before use.
Usage Precautions
•Make sure that the voltage applied is within the specified range,
otherwise the internal elements of the counter may be damaged.
•The load current must be within the rated current.
•Ensure that the power is turned OFF before changing DIP switch
settings. Changing DIP switch settings with the power turned ON
may result in electric shock due to contact with terminals subject to
high voltages.
•Pay attention to terminal polarity to ensure correct wiring.
•Make sure that the fluctuation of the supply voltage is within the
permissible range.
•Apply the power supply voltage through a relay or switch in such a
way that the voltage reaches the rated value within 2 s. If the
voltage is applied gradually, the power may not be reset or unstable
output operations may result.
•Set each set value to match the item being counted (or measured).
Not matching the content of the set values with the counted (or
measured) items may cause unexpected operations resulting in
injury or damage to the equipment.
•Leaving the H7CX with outputs ON at a high temperature for a long
time may hasten the degradation of internal parts (such as
electrolytic capacitors). Therefore, use the product in combination
with relays and avoid leaving the product as long as more than 1
month with the output turned ON.
•When the product is operated with no-voltage input (NPN input),
approximately 14 V is output from the input terminals, so connect a
diode if the external power supply is less than 14 V.
•Install a switch or circuit-breaker that allows the operator to
immediately turn OFF the power, and make sure it is labeled
clearly.
•The H7CX’s panel surface is water-resistive (conforming to NEMA
4, UL Type 4X, and IP66). In order to prevent the internal circuit
from water penetration through the space between the H7CX and
operating panel, attach a waterproof packing between the H7CX
and installation panel and secure the waterproof packing with the
Y92F-30 Flush-mounting Adapter.
•Tighten the two mounting screws on the Adapter. Tighten them
alternately, a little at a time, so as to keep them at an equal
tightness. If the panel screws are tightened unequally, water may
ingress inside the panel.

■Precautions for Correct Use
External Power Supply
The capacity of the external power supply is 100 mA at 12 V. When
using a 24 VAC/12 to 24 VDC power supply, reduce the load with the
power supply voltage, as shown in the following diagram (DC power
supplies only).
Power Supplies
•Turn the power ON and OFF using a relay with a rated capacity of
10 A minimum to prevent contact deterioration due to inrush current
caused by turning the power ON and OFF.
•Be sure that the capacity of the power supply is large enough,
otherwise the H7CX may not start due to inrush current (reference
value: approx. 10 A, 1.5 ms at 26.4 VAC) that may flow for an
instant when the H7CX is turned ON.
Power Failure Backup
All data is stored in the EEPROM when there is a power failure. The
EEPROM can be overwritten more than 100,000 times. EEPROM is
overwritten when the power is turned OFF or when settings are
changed.
■Conformance to EN/IEC
Standards
•Specifications call for basic insulation between the power supply
and input terminals, between the power supply and output
terminals, and between the input and output terminals. (The H7CX-
A@D is not insulated between the power supply and input
terminals.)
•Input and output terminals are connected to devices without
exposed charged parts.
•Input and output terminals are connected to devices with basic
insulation that is suitable for the maximum operating voltage.

Safety Precautions (H7CX-A)
■Precautions for Safe Use
Changing the Set Values
When changing the set value during operation, because the H7CX
uses a constant read-in system, output will turn ON if the set value is
equal to the present value.
■Precautions for Correct Use
Power Supplies
When turning the power ON and OFF, input signal reception is
possible, unstable, or impossible as shown in the diagram below.
Transistor Output
The transistor output of the H7CX is isolated from the internal
circuitry by a photocoupler, so the transistor output can be used as
both NPN and PNP output.
The diode connected to the collector of the output transistor is used
to absorb inverted voltage that is generated when an inductive load
is connected to the H7CX.
Operation with a Set Value and Present
Value of 0
If the set value and present value are both 0, output will turn ON.
Output will turn OFF during reset.
Using the Prescaling Function
Observe the following points when setting a prescale value.
•Set the set value to a value less than {Maximum countable value −
Prescale value}.
Example: If the prescale value is 1.25 and the counting range is
0.000 to 999.999, set the set value to a value less than
998.749 (= 999.999 − 1.25).
•If the set value is set to a value greater than this, output will not turn
ON.
Note: Output will turn ON, however, if a present value overflow occurs
(FFFFFF or FFFF).
•Setting the prescale value incorrectly may result in incorrect
counting operation. Be sure to set the prescale value correctly.
Response Delay Time When Resetting
(Transistor Output)
The following table shows the delay from when the reset signal is
input until the output is turned OFF.

Safety Precautions (H7CX-R)
■Precautions for Safe Use
Changing the Measurement Value
The H7CX-R uses a constant read-in system, so the output status is
affected when the comparison values are changed during operation
such that the present measurement value falls within the range of the
upper- and lower-limit comparison values.
Turning ON the Power using the
Factory Settings
When the power is turned ON using the factory settings, the output
will turn ON after 999.9 s if no pulses are received as count input.
■Precautions for Correct Use
Comparison Value Settings
In upper and lower limit output mode, if the comparison value setting
is such that comparison value 1 ≥ comparison value 2, the output will
always be ON.
Using the Prescaling Function
Setting the prescale value incorrectly may result in incorrect counting
operation. Be sure to set the prescale value correctly.
