 Product Description

ZCM-31 digital time programmers are used to realize time functions in automation and control systems.

Switching on / off the device is related to sunset and sunrise (official dawn and dusk).

The following information on geographic coordinates of the clock’s installation place, current date, and time difference with regard to the universal time (GMT) is used to calculate the time of sunrise and sunset.

Additionally, the system has the function of a programmable night break and a possibility to change the calculated sunrise/sunset time in the range of ±120 min.

The device casing construction allows the system to be installed on a TH35 rail and additionally the casing can be sealed.

The system structure guarantees battery backup of the settings in case of power supply failure.
