Executing complex sequential control logic in rugged industrial environments is the primary role of the Mitsubishi Electric FX2N-64MR-DS, a high-density, DC-powered programmable logic controller base unit. Engineered to handle intensive local automation tasks, this controller integrates 32 digital inputs (24V DC) and 32 relay outputs within a highly compact form factor. Running on a 24V DC nominal power source, this base unit is optimized for field panels, remote installations, and mobile or backup power systems where standard AC mains are unavailable. Its internal architecture supports rapid instruction execution and is fully expandable with special functional blocks, analog converters, and network communication modules from the MELSEC FX2N ecosystem.

The FX2N-64MR-DS base unit utilizes a 24V DC input supply, differing critically from the FX2N-64MR-ES/UL version which operates on standard 100-240V AC. Ensure control panels are correctly pre-wired for DC distribution before direct unit mounting. While the legacy FX2N series programs can be uploaded and integrated directly via standard RS-422 programming adapters, modernizing installations to newer FX3U or FX5U series requires systematic I/O map verification and project-level program compilation conversion within GX Works2 or GX Works3 software.
Unlike its AC-powered counterparts, the DC-powered FX2N-64MR-DS base unit does not include an auxiliary 24V DC sensor output terminal. System designers must include an external, dedicated power distribution block or power supply to source operational voltage for passive field transmitters, limit switches, and photocells. Furthermore, when switching high inductive loads like DC-driven motor starters or solenoids through the onboard relays, back-EMF protection (flyback diodes across the load) must be implemented to preserve terminal contact life and prevent high-frequency noise interference.
To configure inputs as sink type (NPN), hook up the 'S/S' terminal directly to the external 24V DC supply terminal. Conversely, for source type (PNP) input configurations, link the 'S/S' terminal directly to the 0V reference terminal. For critical analog modules situated on the FX expansion bus, ensure proper functional earthing by connecting the controller's PE terminal to your main ground bus using the shortest possible length of 14 AWG wire.
Mount the base unit vertically on a standard 35mm DIN rail or secure it to a steel backplate using M4 chassis screws, ensuring at least 50mm of clearance around the upper, lower, and side vents for natural thermal dissipation.
Wire the main 24V DC supply lines to the dedicated power terminals. Verify positive and negative polarities before testing active power to avoid circuit damage.
Attach the required expansion ribbon cables and lock them securely into the right-hand side expansion bus port before closing the terminal layout covers.
