Time relay ERD-96 ERD-48, ERD-72 - TENSE

Delay timer / cyclic pulse relay / symmetrical and asymmetrical pulse generator

The ERD-96 ERD-48, ERD-72 timer relay is used to create a time delay or generate cyclic pulses to control various processes in automation and control systems (ACS).
Particularly suitable for:

• Alternating current systems,

• swimming pool and technology control,

• emergency and security systems,

• general automation and sequential plant control.

Main features

• Two basic functions

  • Delayed timer
