Character height of 10 mm with a wide viewing angle.
Operation is simplified by the Up Key for each digit.
Power supply circuit and input circuits are isolated inside the counter.
Previous non-isolated counters had wiring restrictions and could be damaged if wired incorrectly. The H7CZ removes these worries.
You can set an upper limit for the set value to prevent unexpected operation of output devices caused by setting mistakes.
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 or the load.
Worry-free application is possible in locations subject to water.
Note: When the Y92S-29 waterproof packing is used.
Select from any of seven protection patterns. Use the best one for the application.

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 horizontally mount Timers side by side. Attach the Flush Mounting Adapters so that the surfaces
without hooks are on the sides of the Timers. If they are mounted side-by-side, water-resistance will be lost.
* These dimensions depend on the kind of DIN Track. (Reference value)
