Features
Basic Features
Ultra Short Body
The body depth has been greatly reduced. Helps in making thinner
control panels.
Easier to Read
For better readability, the character height for the present value
display is 12 mm on models with 4 digits, the largest class in the
industry. The wide viewing angle and brightness provide excellent
visibility. The number of display segments has also been increased to
make settings easier to understand, and the present value display
can be switched between red, green, and orange so that output status
can be seen from a distance.
Note: The display color can be switched on all models except for the
H7CX-A11 and H7CX-R11.
The Easiest Operation
Operation is simplified by the
Up/Down Key for each digit
on 4-digit models and Up
Key for each digit on 6-digit
models.
Safety and Reliability
Isolated Power Supply and Input Circuits
Power supply circuit and input circuits are isolated inside the Counter/
Tachometer. Previous non-isolated counters had wiring restrictions
and could be damaged if wired incorrectly. The H7CX removes these
worries.
Note: Except 12 to 24-VDC models.
Set Value Limit
You can set an upper limit for the set value to prevent unexpected
operation of output devices caused by setting mistakes.
Output Counter
The output counter counts the number of times the output turns ON
(alarms can be displayed and the count can be monitored in
increments of 1,000 operations). This counter is useful in managing
the service life of the Counter/Tachometer or the load.
Refer to Safety Precautions on page 52.
12 to 24-VDC Models with Screw Terminals: 59 mm
100 to 240-VAC Models with Screw Terminals: 78 mm*
Models with Sockets: 63.7 mm (case dimension)

separately) with a different color to match the installation site. Select
from black, white, and light gray (except for models with tachometer
function only).
Universal NPN/PNP Input
DC 2-wire sensors can be connected for a wide range of input
devices.
Waterproof, Dust-proof Structure (UL508 Type
4X and IP66)
Worry-free application is possible in locations subject to water.
Note: When the Y92S-29 Waterproof Packing is used.
Key Protection

Confirm that the power supply meets specifications before use.
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.

Panel Cutouts
Panel cutouts are as shown below. (according
to DIN43700).
Note: 1. The mounting panel thickness
should be 1 to 5 mm.
2. To allow easier operation, it is
recommended that Adapters be
mounted so that the gap between
sides with hooks is at least 15 mm
(i.e., with the panel cutouts
separated by 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-
resistance will be lost.

Front Panel (Replacement Part)
You can change the color of the Front Panel when mounting the
Counter/Tachometer. The Counter/Tachometer is shipped with a
black (N1.5) Front Panel. "COUNTER" is printed on the front of
Replacement Front Panels.
Protecting the Counter/Tachometer in Environments
Subject to Oil
The Waterproof Packing will deteriorate, harden, and shrink
depending on the application environment. To ensure maintaining the
IP@6, UL Type 4X waterproof level, periodically replace the
Waterproof Packing. The periodic replacement period will depend on
the application environment. You must confirm the proper
replacement period. Use 1 year or less as a guideline. If the
Waterproof Packing is not replaced periodically, the waterproof level
will not be maintained. It is not necessary to mount the Waterproof
Packing if waterproof construction is not required.
Note: 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.

The H7CX's panel surface is water-resistive (conforming to IP@6,
UL Type 4X) and so even if drops of water penetrate the gaps
between 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 IP54F against oil. Do not, however, use the
H7CX in locations where it would come in direct contact with oil.

Explanation of Functions
Items marked with stars ★can be set using the DIP switch.
Input Mode (cntm)★
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 page 21.)
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.
ADD: Dual count value = CP1 PV + CP2 PV
SUB: Dual count value = CP1 PV −CP2 PV
Output Mode (outm)★
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
output 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 page 22.)
One-shot Output Time (otim)★
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)★
Set the one-shot output time (0.01 to 99.99 s) for control output
(OUT2).
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 1 Time (otm1)
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.
Counting Speed (cnts)★
Set the maximum counting speed (30 Hz/5 kHz) for CP1 and CP2
inputs together.
If contacts are used for input signals, set the counting speed to 30 Hz.
Processing to eliminate chattering is performed for this setting.
Reset Input Signal Width (iflt)★
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 the input signal, set the input signal width to
20 ms. Processing to eliminate chattering 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).
• 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.
• Output will turn ON, however, if a present value overflow occurs
(FFFFFF or FFFF).
NPN/PNP Input Mode (imod)
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
page 9.
Display Color (colr) (Displayed for terminal block models
(except H7CX-A11@) only.)
Set the color used for the present value.
* Output 2 for 2-stage models.
With the twin counter, output 1 and output 2 will both turn OFF when
the output status is OFF. Either output 1 or output 2 will turn ON when
the output status is ON.

Counter
Absolute Value Setting/Forecast Value Setting (setm)
For the 2 count output mode, an absolute value setting (abs) or
forecast value setting (ofst) can be set for set value 1.
When a forecast value is set, specify the forecast value set value (i.e.,
the deviation for the set value).
The forecast output (output 1) turns ON when the present value
reaches the forecast value.
If the forecast set value is greater than or equal to the set value, the
forecast output (output 1) will turn ON as soon as counting starts.
If the forecast value setting is used, specify the set value 2 minus the
forecast value setting for set value 1.
Set Value Upper Limit (sl-h)
Set the upper limit for the set value when it is set in run mode.
The setting can be made from 1 to 9999 for 4-digit models and from
1 to 999999 for 6-digit models.
Forecast Set Upper Limit (pl-h)
Set the upper limit for the forecast set value.
The setting can be made from 1 to 9999 for 4-digit models and from
1 to 999999 for 6-digit models.
Batch Count Upper Limit (bl-h)
Set the upper limit for the batch count value. The setting can be made
from 1 to 9999 for 4-digit models and from 1 to 999999 for 6-digit
models.
Output Allocation (otst)
When using an H7CX-AU@-N model as a 2-stage counter, the output
can be flexibly allocated to either stage 1 or 2.
The transistor output can be allocated to SV1 and the contact output
to SV2 or vice verse, as in the following tables.

The limit can be set to between 0 ×1000 (0 times) and 9999 ×1000
(9,999,000 times). Only the underlined values are set. The alarm will
be disabled if 0 is set.
If the total ON count of the output exceeds the alarm set value, e3
will be displayed on the Timer to indicate that the output ON count
alarm value was exceeded. Refer to Self-diagnostic Function on page
page 36 for information on the e3 display.
ON Count Alarm Set Values for Outputs 1 and 2 (OUT1
and OUT2) (on1a and on2a)
