  WDE4-U200 relay – Timer, one-shot, 4 pole

  Plug-in electronic railway one-shot timer relay with four change-over contacts. When the relay is activated the coil is energized with one pulse. The pulse time is adjustable with a lockable knob. The relay can also be suplied with a fixed pulse time (no knob). The relay is equipped with two LEDs which indicate the presence of power supply and the energizing of the contacts. Also standard equipped with magnetic arc…
