Timed Relays ERD-96 ERD-48, ERD-72 - TENSE

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

The ERD-96 ERD-48, ERD-72 timed relay is designed to create a delay or generate cyclic pulses to control various processes in automation and control systems (ACS).
It is particularly suitable for use in:

• HVAC systems,

• swimming pool and technology control,

• emergency and safety systems,

• general automation and sequential plant control.

Key Features

• Two basic functions

  • Delay timer

  • Cyclic relay (pulse generator - symmetrical/asymmetrical pulses)

• Wide time range:
  0.1 s to 999 minutes

• Countdown indication - digital display of remaining time (cooldown time)

• Simple connection via terminal block

• Suitable for universal use in 100...240 V AC networks
