TGKAB Timers

TGKAB series Cube Relay Repeat-Cycle On/Off timers are a unique combination of solid-state timing circuitry with a relay output in a compact 2" x 2" configuration. These solid-state timers offer the many advantages of a relay output and provide the same functional performance as plug-in relay timers, but at significant cost savings. Terminal #2 is common for both the input voltage and the load, thereby saving on installation cost.


Timing Mode

Application of input voltage to the timer starts the “On” time delay, and energizes the load. At the end of the “On” time delay, the load is de-energized, and the “Off” time delay starts. At the end of the “Off” time delay, the load is again energized, the timer returns to the “On” time delay, and the cycling continues as long as input voltage is applied. Removal of the input voltage resets the timer.
