A16B-3200-0110 is a power/signal interface module designed by Fanuc specifically for CNC systems (such as 0i series, 18i series and other high-end CNC systems). Its core function is to provide stable power distribution for CNC systems, signal interaction interfaces for external devices (such as servo drives, spindle drives, operation panels), and system operation status monitoring. It is the "signal hub" for CNC equipment (such as machining centers, lathes, milling machines) to achieve precise motion control.
