Fanuc A16B-1310-0010 I/O Rack Power Supply Unit

The Fanuc A16B-1310-0010 is a dedicated I/O rack power supply designed for use with Fanuc CNC systems. This power supply unit provides regulated DC power to I/O modules and other components within the A16B series architecture. It is specifically compatible with Fanuc Series 11 and Series 15 control systems, delivering reliable power distribution for machine tool automation.

Output Specifications

The A16B-1310-0010 power supply provides multiple DC output voltages to support various I/O modules and peripheral components. Output ratings include 5V DC at 5A, 5V DC at an additional output, 0.5A, and 2A outputs to accommodate different load requirements. The unit is designed to supply power to Fanuc A03B series yellow modules, including AC type interfaces and positioning modules. All outputs are regulated to ensure stable operation of connected CNC components.

Input Voltage Requirements

The power supply accepts three-phase AC input voltage options of 200V, 220V, or 250V AC, with tolerance of +10% to -15%. It is designed for industrial electrical environments, providing adequate input filtering to reject power line disturbances commonly found on factory floors. The input range allows flexible deployment in regions with different mains voltages.

Compatibility with CNC Systems

This power supply is engineered specifically for Fanuc Series 11 and Series 15 CNC (Computer Numerical Control) systems. It serves as the I/O panel power source, delivering DC power for PLC communication, digital input/output modules, and other peripheral devices within the control rack. The unit works with the standard Fanuc I/O rack configuration, integrating seamlessly with A16B-1310 series modules. It provides the necessary power rails for both logic-level operations and field I/O signaling.

Design and Construction

The A16B-1310-0010 features a robust chassis design suitable for industrial environments. The enclosure provides EMI/RFI shielding to prevent electromagnetic interference with sensitive CNC control signals. The power supply includes overvoltage and overcurrent protection to safeguard downstream modules. Status indicators on the front panel provide visual confirmation of power output presence and fault conditions. A maintenance-free design eliminates the need for periodic adjustments, and contact-less components contribute to extended service life.

Integration with Fanuc Components

This power supply is designed to be mounted on the I/O rack alongside other Fanuc A16B series modules, including the IF01D I/O interface card and other positioning control modules. It interfaces with the rack via standard backplane connectors, providing power distribution across the entire I/O assembly. The unit may supply DC 300V power to spindle amplifiers and servo amplifiers when used in conjunction with appropriate power transformer configurations. When using the Fanuc standard power transformer, input voltages of 200V, 220V, 230V, 240V, 380V, 415V, 440V, 450V, 480V, and 550V can be accommodated.

Diagnostic Indicators

The A16B-1310-0010 includes LED status indicators that show power supply health, output presence, and error conditions. Abnormal conditions such as overcurrent, overvoltage, or output shorts are indicated by specific LED patterns as defined in Fanuc diagnostic documentation. These diagnostic features assist maintenance personnel in quickly identifying faults for reduced downtime.

Applications

This power supply is essential for maintaining operation of older Fanuc CNC machines, including machining centers, lathes, and milling machines equipped with Series 11 or 15 controls. It is also used in system rebuilds and as a replacement part for legacy equipment where the original power supply has degraded.
