FANUC A20B--0150 Emergency Stop Control Board

The FANUC A20B-0150 Emergency Stop Control Board is a dedicated safety module for FANUC automation systems that processes emergency-stop signals to initiate a halt in connected equipment. This part, identified by the A20B-0150 designation, serves as the interface within the FANUC control network for emergency-stop (E-stop) functions, coordinating with safety interlocks and other control hardware to enforce a stop when triggered. In typical CNC and robotics environments powered by FANUC controllers, it plays a critical role in stopping motion and changing system state in response to operator or safety-triggered events. The part title clearly communicates its purpose and part-number identity, supporting accurate selection in FANUC catalogs and service documentation. In practice, technicians rely on the exact part number to match spare parts in repair operations and to ensure compatibility with FANUC controllers and safety networks.
