Cube Relay Delay On Break Timers - TGMB Timers

Cube Relay Delay On Break Timers
TGMB Timers

TGMB series Cube Relay Delay on Break timers are a unique combination of digital CMOS timing circuitry with a relay output in a compact 2" x 2" configuration. For users of solid-state timers, these units provide the same functional performance as plug-in relay timers, but at significant cost savings. The TGMB relay common is internally hooked to (+) or hot.


Timing Mode

Input voltage is applied continuously. Upon closure of the normally open isolated external initiate switch, the load is energized, and remains energized as long as it is closed. When the external initiate switch opens, the time delay is started. At the end of the time delay, the load is de-energized, and the timer is ready for another cycle.
