TBE Series Single Shot DIP Switch Time Delay Relay

The TBE Series Single Shot DIP Switch Time Delay Relay from the ATC Diversified Electronics division of Marsh Bellofram is a family of rugged, high-reliability single shot DIP switch time delay relays (TDRs), designed to equip industrial machinery, conveyor belts, exhaust fans, heating systems, lubricators, and pump and motor controls with timed sequence delay, soft-start delay or auto-start functions for added machinery and equipment protection.

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.  Supply voltage is continuously applied to the input. An external control isolated switch between pins 5 and 6 initiates the time delay. When closed (momentary or maintained), the relay energizes and the delay period begins. Upon completion of the delay period, the relay de-energizes. NOTE: The TBE Series is available in 8-pin SPDT and 11-pin DPDT configurations.
