Allen-Bradley 800T-XD1 Pushbutton Contact Block is a shallow, 30 mm accessory that adds a single normally open contact to Allen-Bradley 800T/H 30 mm pushbutton operators, enabling simple control logic directly at the operator station. Identified in catalogs as a “Contact Block Shallow 1NO,” the XD1 is designed for use with Bulletin 800T and 800H 30 mm control stations, making it suitable for start/stop interlocks or gating circuits in industrial panels. Its compact, 1NO configuration integrates into standard 30 mm assemblies to provide a dedicated normally open contact without additional external hardware.
