The Fanuc A03B-0819-C104, also identified by its model designation AID16D, is a 16 point digital input module designed for use with Fanuc Series 16i, 18i, and 21i CNC control systems. This module operates on a 24 VDC supply and provides a response time of approximately 20 milliseconds, making it suitable for interfacing discrete sensor and switch inputs to the machine control. The unit is part of the A03B series modular I/O architecture and mounts to a compatible Fanuc B model I/O backplane. Connection is made through screw terminal connectors located behind a hinged terminal cover. The nameplate identifies this unit as serial number N112671 with a date code of 2005 02, manufactured by Fanuc Ltd in Japan. The module carries CE marking and EMC compliance markings as shown on the rating label. Typical applications include CNC machining centers, turning centers, and other industrial automation systems where reliable discrete input handling is required for limit switches, proximity sensors, pushbuttons, and similar field devices. The AID16D designation refers to the 16 point digital input configuration with a 20 ms input filter time. Alternate Fanuc part numbers associated with this same physical assembly include A03B-0807-J104 and A03B-0807-C104. This part number is commonly specified as a direct replacement in Fanuc CNC I/O assemblies and is interchangeable with other AID16D modules of the same revision when used on the same backplane configuration.
