FANUC A16B-2202-0542 Wiring PCB

Overview

The A16B-2202-0542 is a FANUC wiring PCB in the A16B-2202 board family. FANUC alpha-series maintenance documentation identifies this exact board as the wiring PCB for 6081 power supply hardware, and public industrial listings also describe it as a power PCB control board.

That places the board on the power-supply side of the installed drive system rather than in the CPU, memory, or general I/O category.

This board is relevant where the installed FANUC drive or servo hardware already depends on the original 6081 power-supply wiring-board structure.

In board-level service work, a power-supply wiring PCB is selected by exact part number and hardware position because it belongs to the internal power section of the control assembly. 

Keeping the same model helps preserve the original board function and fit inside the power-supply hardware.

Technical Data

Application Value

This board is suited to FANUC power-supply and servo-drive hardware where the installed system already uses the 6081 power-supply board arrangement.

It is especially relevant in repair, refurbishment, and board replacement where the machine already depends on the original wiring-board position inside the power section.

Because the published references tie the board directly to the power-supply structure, it should be treated as a dedicated internal board rather than as a generic spare PCB.

Matching the same board number helps preserve the original power-board layout and service path.

Selection Notes

The most important checks are the exact part number, the A16B-2202 family, and the published identification of the board as a wiring PCB for 6081 power supply.

Where the installed system already uses that same power-supply structure, these are the main compatibility points.

FAQ

Q1: What kind of board is A16B-2202-0542?
It is a FANUC wiring PCB. FANUC maintenance material identifies it specifically as the wiring PCB for 6081 power supply hardware, and public industrial listings also place it in the power PCB control board category.

That means it belongs to the power side of the installed system rather than to CPU or I/O hardware.

Q2: Why is the 6081 power-supply reference important?
Because that is the clearest published hardware role for this board. The maintenance-manual references tie A16B-2202-0542 directly to the 6081 power-supply configuration, which is the main reason this board should be matched by exact installed function rather than by appearance alone.

Q3: Is this a control CPU board or a power-side board?
The published references place it on the power-side wiring-board level. That matters in service work because a board in the power section has a very different role from a main control PCB or an I/O board.

The exact board role should stay unchanged when replacing it.

Q4: Why does exact model matching matter on this board?
Because the board is tied to a specific internal power-supply configuration. Public references do not present it as a generic PCB; they identify it by exact part number and by the 6081 power-supply wiring-board role.

That exact match is the safest way to keep the installed hardware structure consistent.

Q5: What should be checked before ordering?
Check the installed part number, confirm that the original board is A16B-2202-0542, and verify that the installed hardware uses the same 6081 power-supply board position.

Those are the main compatibility points supported by the published references for this model.
