FANUC A03B-0819-C011 IO Module with 16 Digital Outputs 24V DC and Modular Expansion Support

The FANUC A03B-0819-C011 module is an Interface Module (often designated as AIF01A) for the FANUC I/O Link communication system. It serves as a communication gateway to connect a CNC controller to various I/O devices.

• Model & Designation: A03B-0819-C011, also known as an AIF01A interface module
• Primary Function: Acts as the interface between a FANUC CNC and field devices like sensors, switches, relays, and actuators. Functions as an I/O Link master for connecting to the CNC controller
• Voltage: Operates on a standard industrial 24V DC power supply

• Protocol: Uses the FANUC proprietary I/O Link protocol for fast, deterministic communication. Some listings mention compatibility with RS-232C/RS-485 protocols
• System Compatibility: Commonly compatible with FANUC controls, including the 0i, 16i, 18i, and 21i series
• Physical Installation: Designed for rack/slot-based installation within a FANUC control cabinet. Requires shielded, twisted-pair wiring for reliable communication

• Other Functions: Some vendor listings categorize it as a Digital Input Module with 16 input points, or as a general-purpose I/O Module with both input and output capabilities
• Note on Configuration: A few sources describe this module as an I/O Power Module, though most evidence indicates it functions as a communication interface module
