Allen-Bradley 800T-XA is a shallow 30 mm depth contact block that adds a dual-contact set to Bulletin 800T/800H push-button stations, delivering 1 normally open (NO) and 1 normally closed (NC) contact. The block mounts behind the actuator (white or black) and its NO and NC contacts can be wired in parallel to support simple interlock or stop/start circuits. Designed for 14-18 AWG conductors (0.5-2.5 mm2), it is an official 800T accessory that expands the control inputs without adding significant panel depth.
