Product Information

Product Application

The FANUC A20B-8101-0350 DeviceNet PC104 interface board is mainly used for compatible FANUC robot control systems. It may be required when the original DeviceNet interface board is damaged, unstable, disconnected, or causing robot communication, fieldbus, or I/O network-related faults.

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

Quality Control and Testing

For FANUC DeviceNet interface boards and robot controller 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-8101-0350. Similar FANUC communication boards may have different interface types, hardware versions, connector layouts, mounting clips, controller compatibility, DeviceNet settings, or software requirements.

Please pay special attention to the DeviceNet / DNET interface description, PC104 board type, and rack mounting clip. If you are not sure whether this FANUC DeviceNet PC104 interface board is suitable for your robot controller, please send photos of the original board label, connector side photos, robot controller model, communication configuration, and alarm information. REACO CNC can help check the details before purchase.
