Mitsubishi FX2N-128MR PLC Base Unit for MELSEC-F Series

The Mitsubishi FX2N-128MR (FX2N-128MR) is a high-capacity programmable logic controller base unit engineered for the MELSEC-F FX2N series. Designed to serve as the central processing and control hub within industrial automation setups, this main unit delivers integrated control capability across manufacturing, material handling, assembly lines, and machine tool systems. This base module features a total of 128 combined digital input and output channels, comprising 64 digital inputs operating at 24 V DC alongside 64 digital outputs equipped with normally open relay contacts. Functionally equivalent to the FX2N128MRESUL configuration, the unit coordinates discrete field devices, sensors, and actuators to execute programmed logic reliably across factory processes. With its extensive allocation of 64 inputs and 64 relay contact outputs, the controller enables direct interfacing with switches, indicators, solenoid valves, and external relays. The FX2N-128MR provides robust processing and reliable hardware architecture, making it a critical control component for operating, upgrading, or maintaining Mitsubishi MELSEC-F automation installations.
