GRT8-D On Off Timer Relay

GRT8-D on-off timer relay is a back-up source for Delay OFF in case of voltage failure (emergency lighting, emergency respirator, or protection of el. controlled doors – in case of fire).

  • Time range (adjustable by the rotary switch and fine setting by potentiometer):
    0.1 s – 10 min.
  • Voltage range: AC/DC12-240V , clamp terminals.
  • Relay status is indicated by LED.
  • 1-MODULE,DIN rail mounting.
