Description
📌 FANUC A20B-8200-0395 – ZERO-i Mate C MAIN PCB
What it is:
The A20B-8200-0395 is a main printed circuit board (PCB) used in FANUC CNC controller systems, specifically as the main motherboard for the ZERO-i Mate C series of controllers. It’s part of FANUC’s A20B-8200 family of control PCBs and acts as a central logic/CPU board within the controller hardware.
🔧 Key Description
-
Part Number: A20B-8200-0395
-
Name: ZERO-i Mate C MAIN PCB (Main Control Board)
-
Series: A20B-8200 family of FANUC PCBs
-
Function: Acts as the central processing/mainboard for the ZERO-i Mate C CNC controller — it runs core controller logic, manages communication with peripheral modules, and handles machine control functions.
🛠️ Role & Use
This board is typically installed in the controller cabinet of CNC machines that use the FANUC ZERO-i Mate C series control system. It’s essentially the “brain” of that controller model, coordinating data flow, interfacing with I/O boards, servo systems, and operator panels to execute programs and control motion.
📌 Technical Notes
-
It is often described as a “PCB – Main Board 486” (indicating it uses a 486-class CPU architecture).
-
This part may be sold new, refurbished, or repaired by industrial automation parts suppliers; many offer exchange or repair options for boards like this.
-
Core exchange options for refurbishment are commonly available through parts vendors (send your old unit back to get credit on a rebuilt board).
🏭 Typical Application
Used in older FANUC controller models where the ZERO-i Mate C controller platform is installed (e.g., on certain machining centers or CNC mills/turns that use this entry-level controller series). The board handles the main system logic and communication tasks needed to keep the CNC running.
