GRT8-S1/S2 Asymmetric cycle

GRT8-S1/S2 cycle time relay is used for regular room ventilation, cyclic dehumidification, light control, circulating pumps, noon signs, etc.

  • 2 Time functions:
    cycler beginning with puls.
    cycler beginning with the pause.
  • Function choice is done by an external jumper of terminals S-A1.
  • Time scale 0.1 s – 100 days devided into 10 time ranges:
    (0.1 s – 1 s / 1 s – 10 s / 0.1 min – 1 min / 1 min – 10 min / 0.1 hrs – 1 h / 1 hrs – 10 hrs / 0.1 day – 1 day /1 day – 10 days /3 days – 30 days / 10 days – 100 days).
  • Relay status is indicated by LED.
  • 1-MODULE, DIN rail mounting.
