Mitsubishi FX3U-80MT-ES-A PLC CPU Base Unit for MELSEC-F Series

The Mitsubishi FX3U-80MT-ES-A is a high-performance programmable logic controller (PLC) CPU base unit designed for the MELSEC-F FX3U series. Serving as the core processing engine in automated industrial control systems, this controller manages machine sequences, timing, and digital operations. It provides 80 built-in input and output points, including 40 digital inputs rated for 24 V DC sink or source operation and 40 transistor digital outputs rated for 5 to 30 V DC sink switching at up to 500 mA with a fast 0.2-millisecond response time. The unit supports an overall connection capacity of up to 256 I/O points using expansion modules. The controller features an integrated program memory capacity of 64,000 steps of RAM and includes a built-in RS-422 communication interface for programming, human-machine interface connectivity, and peripheral data exchange. Operating from an AC supply voltage of 100 to 240 V AC, the module utilizes screw terminal blocks for secure field wiring connections. It is engineered for standard DIN rail mounting with an overall width of 285 mm, making it suitable for compact control cabinets in factory automation, packaging machinery, material handling systems, and assembly equipment.
