TRT3F 115v


  • Delay on release
  • Timer relay module with 1 changeover, width 23 mm
  • The input-side transformer offers the following advantages:
    1. High interference voltage protection
    2. Galvanic separation
  • Supply voltage 115V AC with control LED for energised relay
  • Description
  • Ordering information
  • Input data
  • Output data
  • General data

    • The TRT3F is a delay on release timer relay with built-in transformer for harsh networks.
    • The time delay is 3.5 seconds.



    • The 230V supply voltage is connected to terminals A and B.
    • The changeover is located at terminals:
      – F common
      – E normally open contact and
      – G normally closed contact
    • Delay on release: If terminals H and D are jumpered and opened again, the output relay is energised and releases again after the set time.
