Allen-Bradley 800T-X01 Auxiliary Contact Block

The Allen-Bradley 800T-X01 Auxiliary Contact Block is an add-on accessory for 30 mm 800T pushbutton assemblies, designed to extend control circuits with an additional set of contacts while maintaining a 600 V rating for reliable industrial operation. Intended for use with the 800T family of operator devices, the X01 variant fits the same mounting footprint as the standard 800T pushbutton, enabling compact, integrated control stations that can signal PLCs or interlock other equipment without introducing a separate device in the panel. This auxiliary block is commonly paired with the corresponding 800T pushbutton to provide mirrored or separate contact states that support signaling, sequencing, or feedback paths in machine-control circuits. As part of the broader Allen-Bradley 800T ecosystem from Rockwell Automation, the X01 accessory reinforces the modular approach of the 30 mm pushbutton lineup, allowing engineers to tailor STOP/START and safety-related control logic within a single, cohesive control module.
