AH3 Time Delay Relay

AH3 time delay relay is a time-limited type of timer. It has a variety of time setting ranges and voltages you can choose.

  • Customized CMOS IC for low power consumption, high operation stability, and extreme timing accuracy.
  • 5 (NA, NB, NC, ND, NE) timing series available.
  • Each timing series has 4-time ranges, selectable via DIP switch.
  • 2 modes selectable via slide switch: Mode A (2C) for DPDT time-limiting output contacts and Mode B (1A1C) for SPDT instantaneous and time-limiting output contacts.
  • Mounting &Socket:
  • Surface: PF083A(E)
  • Flush: US-08/P3G-08
