The Fanuc A16B-2200-0346 is a PMC-M (Programmable Machine Control) RAM I/O Link printed circuit board designed for Fanuc Series 0-C/0-D CNC systems. This plug-in module serves as the Master/RAM configuration, providing battery-backed RAM for PMC ladder logic, user programs, parameters, and data retention, while supporting I/O Link communication for expanded machine I/O handling and slave module integration. It features industrial-grade components, robust connectors (including CS3, JD1A1/JD1B2), and low-power operation on system-supplied voltages. [stock available]
