FANUC A20B-8101-0350 DeviceNet PC104 Interface PCB

Overview

The A20B-8101-0350 is a FANUC communication/interface PCB in the A20B-8101 family.

It as a DEVICE NET PC 104 INTERFACE PCB, while another product source describes it as a DeviceNet communication board used with FANUC R-30iA, R-30iB, and R-30iB Plus controllers.

That places the board in the communication-interface category of the controller hardware rather than in the main-board or memory-module section.

This model is relevant where the installed robot controller already depends on DeviceNet communication hardware in the same board family.

Because the board is identified publicly as a PC104 interface PCB, the most important replacement principle is to preserve the exact communication-board role already present in the system, especially when the original controller depends on that network interface.

Technical Data

Applications

This board is suited to installed FANUC robot controllers that already use a DeviceNet communication interface in the A20B-8101-0350 board position.

It is especially relevant in communication-board replacement, robot controller repair, and network-interface maintenance where the original DeviceNet structure must remain unchanged.

Replacement Guidance

Before ordering, confirm the installed part number, verify that the controller uses a DeviceNet communication board, and check whether the installed hardware requires the same PC104 interface and any associated daughter card arrangement noted in public listings.

That is the safest way to preserve the original communication setup.

FAQ

Q1: What kind of board is A20B-8101-0350?

It is a FANUC DeviceNet interface PCB. Public industrial listings describe it specifically as a DEVICE NET PC 104 INTERFACE PCB, which places it in the controller communication layer rather than in the CPU or display section.

Q2: Why is the DeviceNet description important?

Because the network type is part of the board’s core identity. A controller that already uses DeviceNet needs the same communication-board class to preserve the installed network structure, and the repeated DeviceNet description is the clearest compatibility clue for this model.

Q3: What does PC104 mean in this context?

Public listings identify this board as a PC104 interface board, which indicates the board format used for the communication hardware in the controller.

In replacement work, that is useful because it helps distinguish the board from other network cards that may belong to the same broader controller family.

Q4: Which controllers is this board commonly associated with?

One public source associates A20B-8101-0350 with FANUC R-30iA, R-30iB, and R-30iB Plus controllers.

That gives the board a clear installed-base application context for communication-board service and replacement.

Q5: What should be checked before ordering?

Check the installed board code, confirm the controller uses DeviceNet, verify that the original board is A20B-8101-0350, and check whether the same daughter card or interface arrangement is required.

Those are the main compatibility points supported by the public listings.
