Auxiliary Relays

ZR20

Pick Up Delay Time Relay

The pick-up delay time relay type ZR 20; is intended for use as a time-lag element for all kinds of control, protection and signal systems (e.g. in star -delta start-up circuits of motors, in automatic control circuits, etc.) Repetition time error is decreased very much thanks to its digital oscilliator. The tİme measuring process is based on pulse counting instead of usual electrolytic capacitors , thus the relays can perform with consistent accuracy over a large number of operations over long periods. On the front the relay has two LEDs for indication,one for indication of starting time and the other for indication of the relay operation.
