Mitsubishi Electric FX3U-128MR/ES-A Programmable Controller

The Mitsubishi Electric FX3U-128MR/ES-A is a high-capacity programmable logic controller (PLC) module designed for industrial automation and scalable machine control. It provides 128 I/O points (64 digital inputs, 64 relay outputs) powered by a 100–240 VAC supply, with 64K steps of program memory and a processing speed of approximately 65 ns per basic instruction. This module includes a built-in RS-422 interface (RS-232/RS-485 via adapters) and supports expansion up to 256 local I/O or 384 with remote I/O, making it suitable for manufacturing automation, large conveyor systems, packaging lines, process control, and material handling where extensive device control and reliable logic execution are essential. Operating from 0 °C to 50–55 °C, storing from -20 °C to 75 °C, with IP10–IP20 protection and battery backup for memory retention, it mounts on DIN rail and typically consumes about 65 W.
