800.727.5646 atcdiversified.com Diversified Electronics TDF Series Time Delay Relays // TDF Series 73 Repeat Cy c l e –OF F Time F ir s t R e l a y Ou t p ut Application of voltage to the input of the timer initiates the OFF time. Upon completion of the OFF time, the relay energizes and the ON time begins. Upon completion of the ON time, the relay de-energizes and one cycle is completed. This OFF/ON cycling continues until voltage is removed from the input. The OFF/ON time periods are independently adjustable.
