-N
Ultra-compact Counter Provides More
Complete Functionality.
Basic Features
• Short body with depth of only 59 mm (for 12 to 24-VDC Models with Screw Terminals).
*1
• Better readability with character height of 12 mm on 4-digit models and 10 mm
on 6-digit models.
• The present value display characters can be switched between red, green, and orange.
*2
Safety and Reliability
• New set value limit and counter functions have been added.
Other Features
• Front Panel can be changed to white or light gray.
*3
• New models with two tachometer inputs and two tachometer outputs have
been added to the series.
*4
*1.For 100 to 240-VAC Models with Screw Terminals: 78 mm, Models with Sockets: 63.7 mm
(case dimension).
*2.The H7CX-A11 and H7CX-R11 have only red characters.
*3.The Front Panel can be replaced with an optional Front Panel (except for Tachometer-only Models).
*4.Only one prescale value provided.

Features
Basic Features
Ultra Short Body
The body depth has been greatly reduced. Helps in making thinner control panels.
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)
* Power supply circuit and input circuits are isolated for safety and reliability.
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.

models
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.

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.
(Display example)
Easy to read from the top, bottom,
and sides!
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.

Other Features
The front color can be changed simply by
replacing the Front Panel.
The Front Panel can be replaced with an optional Front Panel (sold
separately) with a different color to match the installation site. Select
from black, white, and light gray (except for models with tachometer
function only).
Key Protection
Select from any of seven protection patterns. Use the best one for the
application.
New Functions
Many useful functions have been added, including a Twin Counter
Mode and many tachometer functions to handle even more
applications.
New Tachometer Functions
• Control with two independent inputs (independent measurements,
differential, absolute ratio, and error ratio)
• Peak/bottom hold function
• Output hysteresis setting
• Output OFF delay
• Switching the measurement method (pulse cycle/pulse width)
• Startup time
• Auto-zero time
• Averaging method/Number of averaging times
• AMD-compatible Mode
Note:
Refer to
“Model Configuration”
below, for details on applicable
functions.

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.
