FANUC A03B-0819-C161 (AOR16G) 250 VAC / 30 VDC I/O Relay Output Module m00023

The Fanuc A03B-0819-C161, model AOR16G, is a 16 point relay output module used in the Fanuc Model A I/O system for Series 16i, 18i, and 21i CNC controls. The module provides 16 discrete relay outputs rated at 2 amps per point, with switching capability of 250 VAC and 30 VDC, making it suitable for interfacing CNC logic with solenoids, contactors, indicator lamps, and other discrete field devices. The unit mounts to an ABU05A or ABU10A base unit backplane and connects via a hinged terminal cover for field wiring access. Nameplate data confirms type A03B-0819-C161, model AOR16G, serial number N38773, with a 2003 11 date code. The housing is the standard yellow Fanuc I/O enclosure, manufactured in Japan, and the module carries CE and EMC compliance markings. This part number is commonly deployed in machine tool I/O racks, robot controllers, robotic automation cells, material handling systems, and industrial electrical panel builds where Fanuc Model A I/O architecture is in use. The relay output configuration is appropriate where galvanic isolation between the CNC logic and external loads is required, and the higher voltage and current rating allows direct switching of loads that solid state output modules cannot support. Application compatibility extends across the broader Fanuc Model B generation I/O platform, and the module can serve as a direct functional replacement for an existing AOR16G in service.
