FANUC A20B-2100-0130 Main Board

Overview

The A20B-2100-0130 is a FANUC board-level spare in the A20B-2100 family. Public industrial listings identify it as a main board, while other resale listings describe it as a power board.

Because these sources consistently place it in the core-board category rather than in the accessory or signal-module category, the safest and most accurate positioning is as a main board / power-board level component for compatible FANUC hardware.

This type of board is typically relevant where the installed control depends on the original central board structure of the A20B-2100 family.

In replacement work, a main board has a broader role inside the control unit than a simple daughter board or accessory PCB, which is why exact model confirmation is especially important before ordering.

Technical Data

Application Value

This board is suited to installed FANUC control hardware where the system already uses the A20B-2100 board family and where the original board-level core structure must be preserved.

Because public sources identify it at the main board / power board level, it is especially relevant in repair, refurbishment, and board replacement of existing FANUC control assemblies.

It is also important in lifecycle support.

One public source lists the model as discontinued by manufacturer, which reinforces its role as a maintenance and replacement item for installed equipment rather than as a current mainstream board for new builds.

Selection Notes

The main checks are the exact part number, the A20B-2100 series, and whether the installed board is identified in the hardware as the same main board / power board class.

These are the core match points supported by the public listings for this model.

FAQ

Q1: What kind of board is A20B-2100-0130?
It is a FANUC board-level spare publicly described as a main board and also as a power board.

Those descriptions place it in the core-board section of the control hardware rather than in a simple accessory or I/O-only category.

Q2: Why do public sources describe it as both a main board and a power board?
Public resale sources use both descriptions for this model. Since both labels place the part in the core-board category of the control unit, the safest practical approach is to verify the exact installed hardware position and keep the same board model.

Q3: Why is exact model matching important for this board?
Because a board described as a main board or power board belongs to a central section of the installed hardware.

Replacing it with the wrong board can change the structure of the control unit, so the exact part number is the most important compatibility point.

Q4: Is this model still current?
One public industrial parts source lists A20B-2100-0130 as discontinued by manufacturer.

That makes it particularly relevant to service, maintenance, and installed-base spare-parts support.

Q5: What should be checked before ordering?
Check the full installed part number, confirm the system uses A20B-2100-0130, and verify that the original board is the same main board / power board class in the installed hardware. Those are the main compatibility points supported by the available public references.
