Plug-In Repeat Cycle Timers - TNK Timers
TNK Timers

The TNK Repeat Cycle units meet the needs of customers who require IC digital timing circuits with octal, magnal round and QC bases for plug-in installation. The units are available in SPDT, DPST and DPDT relay forms up to 10 amp with fixed or adjustable time periods.

Timing Mode

Application of input voltage to the timer starts the “Off” time delay. At the end of the “Off” time delay, the “On” time delay starts, and the relay is energized. At the end of “On” time delay the relay is de-energized, the timer returns to the “Off” time delay, and cycling continues as long as input voltage is applied. Removal of the input voltage resets the timer. The “Off” and “On” times are equal.
