Cube Relay Timers - TGCMLB Timers
TGCMLB Timers

TGCMLB series Cube Relay timers are a unique combination of RC timing with a 12 amp relay output in a 2" x 2" configuration without heat sinking. For users of solid-state timers of this type, the TGCML provides equal performance with the additional benefits of no leakage in the “Off” state.

Timing Mode

Power is continuously applied to input voltage terminals. Upon closure of a normally open (N.O.) external initiate switch, the “On” delay time begins. If the switch remains closed for the full time, the load energizes. The load remains energized until the initiate switch is opened, this begins the “Off” delay time. If the switch remains open for the full time, the load de-energizes.
