Delay on Make

On Delay, Delay on Operate, Delay on Energization

  • When power is applied to timer input voltage terminals, the time delay begins
  • When the time delay expires, the timer output relay is energized
  • Input voltage must be removed to reset the time delay and de-energize the timer output relay

Delay on Break

Off Delay, Delay on Release, Delay on De-Energization

  • Power must be applied continuously to timer input voltage terminals and a normally open, dry contact switch attached to timer initiate terminal(s)
  • When the initiate switch closes, the timer output relay is energized
  • When the initiate switch re-opens the time delay begins

Repeat Cycle

Recycle Timer, Recycling Timer, Flasher.

  • When power is applied to timer input voltage terminals, the timer output relay is energized for the duration of time delay
  • When the time delay expires, the timer output relay is de-energized for the duration of time delay
  • Timer output on / off cycling repeats until power is removed from timer input voltage terminals

Single Shot

One Shot

  • Power must be applied continuously to timer input voltage terminals and a normally open, dry contact switch attached to timer initiate terminal(s)
  • When the initiate switch closes, the timer output relay is energized and the time delay begins
  • Opening and closing the initiate switch during the time delay is ignored

Interval On

Interval, Interval Delay

  • When power is applied to the input voltage terminals, the load is energized immediately and the time delay cycle starts
  • At the end of the delay period, the timer transfers back to its pre-power position
  • Removal and re-application of input voltage resets the timer.

True Off

True Off Delay

  • 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.

Anti-Short-Cycle

Anti-Short-Cycle Timer

  • Anti-short-cycle timer prevents premature cycling of compressors in refrigeration, air conditioning and heat pumps, thereby reducing nuisance tripping of fuse or circuit breaker
  • When power is applied (i.e. thermostat closes), the load energizes

Multifunction Relay

  • Wide range of time delay setting using dip switch adjustment or on board potentiometers
  • Available in three separate models covering 12 timing modes and 1-30 amp load switching.
