Time relay ERD-48 - TENSE

Delay Timer / Cyclic Pulse Relay / Symmetrical and Asymmetrical Pulse Generator
Size 48 × 48 mm

The ERD-48 time relay is designed to create time delays or generate cyclic pulses for controlling various processes in automation and control systems (ACS).
It is particularly suitable for use in:

• AC systems,

• swimming pool and technology control,

• emergency and safety systems,

• general automation and sequential equipment control.

Key features

• Two basic functions

  • Power-on delay timer

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

• Wide time range:
  from 0.1 s to 999 minutes

• Time countdown indication - digital display of remaining time (cooling time)

• Simple connection via terminal block

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