The FCUA-DX111 is part of Mitsubishi’s FCUA series of remote I/O cards used with CNC controls such as the M70/M700 family, providing a compact and robust interface between field devices and the CNC controller. It combines 32 channels of 24V DC sink/source digital inputs with 32 channels of 24V DC source digital outputs, allowing it to handle a wide variety of machine signals including limit switches, interlocks, operator panels, and solenoid or relay drive signals. The module connects through Mitsubishi’s dedicated CNC I/O bus and is typically installed in the machine’s electrical cabinet, close to terminal strips to minimize wiring runs and simplify maintenance.
Inputs support both NPN and PNP wiring (sink/source), while outputs provide sourcing 24V DC drive suitable for contactors, relays, indicator lamps, and other low‑power actuators, making it a flexible choice for different machine designs. Built for use in industrial CNC environments, the FCUA-DX111 is designed to withstand vibration and electrical noise common in machine tools, and is commonly supplied with refurbishment or new‑original stock and a 12‑month warranty by aftermarket CNC parts suppliers.
