Timer Relays
A Timer Relay is a combination of an electromechanical output relay and a control circuit. The contacts will open or close before or after a pre-selected, timed interval. Time delay relays are initiated or triggered by one of two methods:*Application of input voltage/auxiliary supply will either initiate the unit or make it ready to initiate when a trigger signal is applied. *Applying a trigger signal is used to initiate the unit after input voltage has been applied. This trigger signal can either be a control switch (dry contact switch) or a power trigger (voltage).
