The Fanuc A03B-0819-C104, also identified as model AID16D, is a digital input I/O module used in Fanuc CNC systems. The module provides 16 discrete input points operating at 24 VDC, with a response time of 20 milliseconds. Signal connections are made through screw terminal connectors mounted behind a hinged terminal door on the front face of the unit. The nameplate confirms the type designation A03B-0819-C104, model AID16D, serial number N112672, and manufacture date code 2005 02, with country of origin Japan. The module is part of the Model B generation of Fanuc I/O units and is commonly installed on A03B series backplanes used with Series 16i, 18i, and 21i controls. Compatible alternate part identifiers include A03B-0807-J104 and A03B-0807-C104. The unit carries CE marking and is built by Fanuc Ltd. Typical applications include reading discrete sensor inputs, limit switches, proximity sensors, pushbuttons, and other 24 VDC control signals from machine tool peripherals back to the CNC. The module mounts into a standard Fanuc I/O slot and communicates with the CNC over the I/O Link interface through the backplane. Operating temperature range is 0 to 55 degrees C, and storage range is 20 below zero to 70 degrees C per Fanuc published specifications. Buyers searching for Fanuc 16 point input modules, AID16D replacement boards, or A03B 0819 C104 spares for legacy 16i, 18i, or 21i installations may find this listing relevant.
