The TDB TUB Series Interval Relay Output from the ATC Diversified Electronics division of Marsh Bellofram is a family of rugged, high-reliability interval relay outputs, 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. When voltage is applied to the input terminals, the TDB TUB Series Interval Relay Output energizes and the time delay begins. Upon completion of the delay period, the relay de-energizes. Reset during or after the delay period is accomplished by removal of the input voltage.
