Mitsubishi FX3U-48MT-ES-A PLC CPU Main Unit for MELSEC-F FX3U Series

The Mitsubishi FX3U-48MT-ES-A (FX3U-48MT-ES-A) is a high-performance programmable logic controller (PLC) main processing unit designed for the MELSEC-F FX3U series. Engineered for complex machine automation, this compact base unit features 48 integrated inputs and outputs, consisting of 24 digital inputs rated at 24 V DC with sink or source wiring flexibility and 24 transistor outputs rated at 5 to 30 V DC with sink switching, delivering a 500 mA load capacity and a rapid 0.2 ms response time. The CPU provides a substantial program memory capacity of 64,000 steps in internal RAM and supports expandable control architecture of up to 256 total I/O points. Equipped with screw terminal blocks for secure field wiring, the unit integrates a built-in RS-422 communication interface for programming, human-machine interface connection, and serial networking. Operating on a universal power supply voltage of 100 to 240 V AC, the controller mounts directly onto standard DIN rail with a frame width of 182 mm. Also referenced as FX3U48MTES, this main unit delivers fast instruction execution, robust reliability, and high flexibility across diverse industrial manufacturing, assembly automation, packaging systems, and material handling applications.
