A16B-1212-0901 Fanuc A16B12120901 New Original control Board

Main Features

Designed for CNC Control Rack Power Support

The A16B-1212-0901 is used inside CNC control systems to support stable power delivery to key rack-mounted modules.

Suitable for System Repair and Replacement

This board is a practical replacement option when the original power supply board has failure symptoms such as unstable startup, power alarm, missing output, or control rack power issues.

Rack-Mounted Board Design

The board is designed for installation in the control rack, normally close to the CPU and I/O board, so the connector layout and installation position should be checked carefully before replacement.

Important for Machine Control Stability

A stable power supply board helps the CNC control system maintain reliable operation, reducing the risk of control faults caused by unstable power distribution.

Full Model Matching Required

Because FANUC boards may look similar across different series, the full model number A16B-1212-0901 should be matched instead of relying only on appearance.

Application Areas

• CNC machine control systems
• FANUC 16 / 18 series control racks
• Robot controller maintenance
• Machine tool electrical repair
• CNC power supply replacement
• Industrial automation equipment service
• Control cabinet troubleshooting
• Production line maintenance

Why Choose This Product

The A16B-1212-0901 is suitable for maintenance projects where the original CNC power supply board must be replaced with the same model. It helps restore power stability in the control rack and supports normal operation of connected control modules.

Before ordering or installation, confirm the machine model, CNC system series, rack location, connector position, input voltage, output voltage and board revision. These checks help reduce mismatch problems and make maintenance work more efficient.
