The A20B-8200-0385 is a FANUC main control board in the A20B-8200 family. It is described as a ZERO i-C MAIN PCB, and another listing identifies it more specifically as F0iC PMC-SB7 W/O POS and F0iC MAIN BOARD.
Those descriptions place it at the center of the CNC control structure rather than in the display, memory, or peripheral-board category.
As a main board, this model is tied directly to the installed control platform. In practical repair work, that makes exact model continuity especially important, because the board defines the core hardware role already used in the machine.

This board is suitable for installed FANUC 0i-C CNC systems where the existing hardware already uses the A20B-8200-0385 main-board structure.
It is especially relevant in controller repair, main-board replacement, and refurbishment where the same control platform and control-board role must be retained.
Before ordering, confirm the installed board code, verify that the control platform is 0i-C / F0iC, and make sure the original board matches A20B-8200-0385 in the same main-board position.
For a control-core board like this, exact board-family and board-role matching is essential.
Q1: What kind of board is A20B-8200-0385?
It is a FANUC main control board. Listings describe it as ZERO i-C MAIN PCB and also as F0iC MAIN BOARD, which clearly places it in the central control section of the CNC system.
Q2: What does “PMC-SB7 W/O POS” mean in the listing description?
That wording appears as part of the board description for this exact model and helps distinguish it from nearby A20B-8200 boards.
In replacement work, these board-level descriptors are useful because they help confirm the correct installed hardware role.
Q3: Is this a peripheral board or a core board?
It is a core board. The model is described as a main board, which means it belongs to the control platform itself rather than to a secondary interface position.
Q4: Why does exact matching matter here?
Because a main control board defines the controller’s platform, internal board hierarchy, and machine-side compatibility.
A substitute that looks similar but belongs to a different role can create configuration or hardware mismatch problems.
Q5: What should be checked before buying?
Check the installed board code, confirm the machine uses the 0i-C / F0iC platform, and verify that the board marking matches A20B-8200-0385 and the same board description family. Those are the main compatibility checks for this model.
