FANUC A16B-1100-0420 02A PC Controller Circuit Board

FANUC A16B-1100-0420 02A PC Controller Circuit Board is a FANUC PC controller module used within FANUC control systems. It is also cataloged as A320-1100-T422, EJ, providing an alternate designation for the same hardware. This PC Controller Circuit Board houses the computer-side control logic and interface circuitry that FANUC controllers rely on to coordinate processing tasks and manage data exchange between control components. In practice, boards like this serve as the computing and signal interface layer that supports the execution of control programs in CNC environments. The dual part numbers—A16B-1100-0420 and A320-1100-T422 (EJ)—aid technicians and engineers in identifying the exact hardware during service, repair, or documentation workflows, reducing the risk of selecting the wrong component. Being a PC controller circuit board, it is designed to integrate with the FANUC control architecture and to support the computer-side operations that drive controller performance, subject to proper installation and system matching.
