TDJ Series On-Delay/Off-Delay Relay Output

Voltage is continuously applied to the input. An external isolated switch controls the timer. When closed, the ON delay T1 begins. Upon completion, the relay energizes. When the switch opens, the OFF delay T2 begins. Upon completion, the relay de-energizes and the cycle is complete. Reset is accomplished by reclosing the control switch after the timing cycle has completed. If the switch opens during the ON delay mode, the relay will remain de-energized and T1 will reset. If the switch is reclosed during the OFF delay mode, the relay will remain energized and T2 will reset. Both delay periods are independently adjustable.
