Cube Relay Repeat Cycle (Dual Adjustable) OFF/ON Timers

TGKDDB series Cube Relay Repeat-Cycle (Dual Adjustable) Off/On timers are a unique combination of solid-state timing circuitry with a relay output in a compact cube configuration. The time delay for both the “Off” cycle and the “On” cycle can be individually adjusted. 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 a significant cost savings.


Timing Mode

Application of power to the input voltage terminals starts the “Off” delay cycle, at the end of the “Off” cycle, load 1 is energized, this is the “On” cycle. At the end of the “On” cycle, load 1 de-energizes and another “Off” cycle starts. At the end of this “Off” cycle, load 2 is energized for an “On” cycle. This alternating output action continues until power is removed.
