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

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

ERD-96 ERD-48, ERD-72 timing relay is designed to create time delays or generate cyclic pulses for controlling various processes in automation and control systems (ACS).
It is especially suitable for use in the following devices:

• AC systems,

• pool and technology control,

• emergency and safety systems,

• general automation and sequential control of devices.

Main features

• Two main functions
