GRT8-A/B Timer On Delay

GRT8-A/B timer on delay is suitable for applications where function and time requirements are known. Time switch, possible to be used for pump decay time after switching the heating off switching of fans.

  • Single-function relay with the possibility of time sitting by a potentiometer.
  • Choice of 2 functions:
    A: Delay ON
    B: Delay OFF
  • Time scale 0.1 s – 10 days divided into 10 ranges.
  • Relay status is indicated by LED.
  • 1-MODULE, DIN rail mounting.
