Mitsubishi FX2-64MR-D Combined Digital I/O Unit for MELSEC FX Series

The Mitsubishi FX2-64MR-D (FX2-64MR-D) is a combined digital input and output base unit designed for Mitsubishi Electric MELSEC-F (FX) series programmable logic controllers. Engineered for robust factory automation and sequential control tasks, this unit integrates 64 total I/O points to streamline machine control and system expansion. The hardware configuration provides 32 digital inputs rated at 24 V DC alongside 32 digital outputs utilizing normally open relay contacts. This architecture allows the controller to reliably interface with discrete industrial sensors, pushbuttons, limit switches, and various field actuators such as contactors, indicator lamps, and solenoid valves. Operating within the MELSEC FX platform, the FX2-64MR-D delivers dependable signal processing and switching performance in automated manufacturing cells, packaging lines, material handling systems, and assembly machinery. Equivalent to FX264MRD, this legacy PLC component supports seamless integration into existing control panels, ensuring stable long-term operation, reduced downtime, and direct signal isolation across diverse industrial automation environments.
