Repeat Cycle-OFF Time

First Relay Output

OPERATION

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.
