True Off

  • Power must be applied continuously to timer input voltage terminals and a normally open, dry contact switch attached to timer initiate terminal(s)
  • When power is removed from timer input voltage terminals, the time delay begins
  • When the time delay expires, the timer output relay is de-energized.


True Off Delay


Application of the supply voltage energizes the output relay. The timing period begins upon removal of the supply voltage. At the conclusion of the timing period, the output relay is de-energized. Reapplication of input voltage before the delay expires resets the time period. Instantaneous Contact option: Application of supply voltage for a minimum of 100 milliseconds initiates time out. Instantaneous contact and timed contacts transfer. Upon removal of supply voltage, instantaneous contact drops out, and timed contacts remain closed for duration of selected time (off-delay) then drop out. Reapplication of power starts the cycle.
