New 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.

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.
Setting the upper limit of the set
value enables worry-free operation.
No overflow
For 1,000 pieces

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.
