TBF Repeat Cycle-OFF Timer First DIP Switch Time Delay Relay
About the TBF Repeat Cycle-OFF Timer First DIP Switch Time Delay Relay from the ATC Diversified Electronics division of Marsh Bellofram Corporation:
When supply voltage is applied to the input, the OFF time (T1) begins. Upon completion of the OFF time, the relay energizes and the ON time (T2) begins. Upon completion of the ON time, the relay de-energizes and one cycle is complete. This OFF/ON cycling continues until supply voltage is removed from the input. The OFF/ON time periods are independently selectable within the same range.
DIP Switch Operation: Digital selection of the time delay is accomplished by the use of ten (10) binary switches, each marked with a time increment. The time periods, of which there are five (5) ranges, represented by each switch in the ON position is added together to obtain the desired time delay. No more trial-by-error adjustments.
