FANUC A20B--0060-R Printed Circuit Board Assembly

FANUC A20B-0060-R Printed Circuit Board Assembly is a control master PCB used in FANUC automation equipment. The part is identified by the A20B-0060-R designation and is described as ZERO C TT CONTROL MASTER PCB Circuit Board. As a Printed Circuit Board Assembly, this unit serves as a central electronic substrate within a FANUC controller, carrying essential circuitry that governs the flow of control signals between modules and sub-systems in the system’s architecture. The term “MASTER” in the description indicates its role as a primary board within the controller, typically coordinating higher-level control functions across connected components. In practice, this FANUC PCB assembly functions as the main control interface in compatible FANUC CNC or automation configurations that require the A20B-0060-R master board, and it is referenced by technicians and service guides when servicing the controller. The designation reflects its place in the product family and supports traceability within FANUC’s replacement-part ecosystem.
