Description
The Littelfuse TDUB3000A Digi-Set Timer is a solid-state delay-on-break time delay relay engineered for precise, dependable control in industrial automation and OEM applications. Powered by digital microcontroller-based circuitry, it delivers exceptional timing accuracy across a universal voltage range of 24–240VAC and 12–24VDC — making it a versatile drop-in solution for a wide range of system configurations.
In delay-on-break operation, the timing cycle initiates the moment the initiate switch is opened. The output stays energized throughout the delay period, then shuts off cleanly at the end of the programmed time — giving you controlled, predictable shutdown sequencing for motors, fans, pumps, and more. DIP switch selectable timing ranges make field configuration fast and straightforward, while high repeat accuracy ensures consistent performance cycle after cycle.
