Allen-Bradley 800T-XT Time Delay Relay 1NO Contact

Allen-Bradley 800T-XT Time Delay Block is a 30 mm contact block accessory for the 800T push-button family that provides a single normally open (1NO) contact with a time-delay function. Intended to mount with 30 mm 800T push-button operators, the 800T-XT adds timed switching capability to control circuits in machines and panels without a separate timer relay. The configuration is 1 NO contact, enabling delayed closure once the associated input is energized, which supports simple sequencing and interlock timing in automated equipment. Built to integrate with the 800T PB lineup, it helps streamline wiring and consolidates control logic in compact installations, making it a practical choice for applications like start/stop sequencing, conveyor indexing, and safety interlocks within industrial automation setups.
