The Fanuc A03B-0819-C104, also designated AID16D, is a digital input I/O module designed for use with Fanuc Series 16i, 18i, and 21i Model B CNC controls. This unit provides 16 discrete digital input points operating at 24 VDC, with a response time of 20 milliseconds. Signal connections are made through screw terminal connectors, allowing sensors, limit switches, proximity devices, and other discrete input signals from the machine tool to interface with the CNC system. The module mounts to a Fanuc A03B series I/O backplane and communicates with the control through the Fanuc I/O Link interface. Operating temperature range is 0 to 55 degrees C, with a storage range of negative 20 to 70 degrees C. Typical applications include machine tool sensor inputs, operator station signal handling, and auxiliary control logic on CNC machining centers, turning centers, and Fanuc powered automation cells. Specifications visible on the nameplate include the model designation AID16D, type A03B-0819-C104, and unit number P045992 with a date code of 2010 08. The serial label N770286 is also present. Alternate Fanuc part numbers commonly referenced for this module include A03B-0807-J104 and A03B-0807-C104. This module is compatible with Fanuc B model I/O backplanes used across a wide range of legacy and current machine tool installations where 24 VDC discrete input expansion is required.
