The Allen-Bradley 800TC-XD4 Contact Block is a 30 mm shallow contact block designed to mount beneath Bulletin 800T pushbuttons and provide one normally closed load-break contact (1-NCLB) in series with a control circuit. It features finger-safe terminals and matches the 800T mounting footprint, making it easy to integrate with 30 mm operator assemblies. This block expands the contact options of 800T stations, enabling interlock and signaling functionality within compact control panels. Typical applications include electrical interlocks, circuit signaling, and feedback wiring in machines that use 800T pushbuttons.
