A20B-8100-0651 FANUC DeviceNet Board Device Net A PCB

The A20B-8100-0651 is a FANUC PC board, commonly described as a DeviceNet board or Device Net A PCB. It is used in compatible FANUC robot control systems for DeviceNet communication, fieldbus connection, and robot system interface applications.

This model is supplied as a FANUC DeviceNet communication board, not a complete robot controller, complete CNC system, or complete drive unit. Correct board number confirmation, robot controller compatibility checking, DeviceNet configuration verification, connector layout checking, and professional testing are important before replacement.

Product Information

Product Application

The FANUC A20B-8100-0651 DeviceNet board is mainly used for compatible FANUC robot control systems. It may be required when the original DeviceNet communication board is damaged, unstable, disconnected, or causing robot communication, fieldbus, I/O network, or interface-related faults.

Because this is a board-level communication component, replacement should be carried out after confirming the original board number, robot controller model, DeviceNet communication configuration, connector layout, and alarm or communication error details.

Quality Control and Testing

For FANUC DeviceNet boards and robot communication PCBs, careful checking is very important before shipment because board condition may directly affect DeviceNet communication, fieldbus connection stability, signal transfer, robot operation, and system reliability. REACO CNC checks qualified products carefully and can provide real product photos or a test video before delivery when required.

Our goal is to help customers receive reliable FANUC robot and CNC spare parts with clear product information, careful inspection, responsive after-sales support, and practical technical assistance.

Compatibility Confirmation

Before ordering, please confirm that the full board number on your original PCB is A20B-8100-0651. Similar FANUC communication boards may have different interface types, hardware versions, connector layouts, controller compatibility, DeviceNet settings, or software requirements.

Please pay special attention to the DeviceNet / Device Net A description. If you are not sure whether this FANUC DeviceNet board is suitable for your robot controller, please send photos of the original board label, connector side photos, robot controller model, DeviceNet configuration, and alarm information. REACO CNC can help check the details before purchase.
