Allen-Bradley 800T-XAY Auxiliary Contact Block

Allen-Bradley 800T-XAY is a 30 mm stackable, sealed auxiliary contact block for the 800T family of pushbutton/operator control devices. It provides two independent contacts: one normally open (NO) and one normally closed (NC), enabling additional feedback or interlock signaling in control circuits. The block is designed to mount directly to 30 mm 800T pushbuttons and can be stacked with other 800T-XAY blocks to expand auxiliary contacts without increasing the overall footprint. As a sealed switch block, it supports reliable operation in demanding industrial environments and easy wiring to PLC inputs or logic circuits. Typical applications include monitoring operator position, implementing interlocks, and furnishing NO/NC feedback in safety or process-control circuits when used with compatible 800T equipment. This part number is part of Allen-Bradley’s 800T auxiliary contact lineup, offering a compact solution for expanding signaling within 30 mm operator assemblies.
