SSAC TDUH3001A Solid State Timer

The SSAC TDUH3001A is an encapsulated solid-state delay-on-make timer designed for on-delay control in process equipment and OEM systems. It accepts universal voltage operation in the 24–240 VAC/DC range and uses a 2‑wire, normally open solid-state output, with load connections selectable to either terminal 3 or 1. The output is rated for a steady 1 A and can handle up to 10 A inrush, making it suitable for switching moderate loads without bulky relays. Timing is set via DIP switches across three selectable ranges, delivering delays from about 0.1 seconds up to approximately 2.8 hours (up to 10,230 seconds) with claimed repeat accuracy around ±0.5%. When input voltage is applied, the timer begins the delay; the output remains de-energized during the interval, then energizes at the end of the delay and stays on until the input is removed. As a purpose-built digital timing module, the TDUH3001A is well-suited to drive process-control sequences, equipment interlocks, conveyors, and HVAC-related controls where compact, reliable solid-state timing is required.
