TGKB Timers

TGKB series Cube Relay Repeat-Cycle Off/On 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.


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 load is energized. When the “On” time delay ends, the load 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.
