| Series Features |
| TBD Series Off-Delay DIP Switch Time Delay Relay |
| Series Description: The TBD Series Off-Delay DIP Switch Time Delay Relay from the ATC Diversified Electronics division of Marsh Bellofram is a family of rugged, high-reliability off-delay 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. Supply voltage is continuously applied to the input. An external isolated switch between pins 5 and 6 controls the timer. When closed, the relay energizes. Opening the switch initiates the delay period. Upon completion of the delay period, the relay de-energizes. If the control switch recloses during the delay period, the relay remains energized and the timer resets to zero. NOTE: The TBD series is available in 8-pin SPDT and 11-pin DPDT configurations. |
