The Mitsubishi FX3U-128MR/ES-A represents the pinnacle of the FX3U compact PLC range. This base unit is designed to handle complex control scenarios that previously required larger, modular PLC systems. With its high-speed processing capabilities—0.065 microseconds per basic instruction—it provides the performance necessary for high-speed machinery and intricate automation sequences.
This model features a massive 128 built-in I/O points, split into 64 digital inputs and 64 relay outputs. The relay outputs provide the flexibility to switch a variety of voltages (both AC and DC), making it suitable for driving a wide range of field devices without additional interface hardware. The "ES-A" designation confirms that the unit is built for the European/Global market, utilizing 100-240V AC power supply.

The FX3U-128MR/ES-A is equipped with 64,000 steps of internal program memory. Beyond its built-in I/O, the system can be expanded up to 384 I/O points using expansion modules and networked I/O. It supports specialized "adapter" modules on its left side for communication and high-speed analog tasks, as well as traditional expansion blocks on its right side, offering unparalleled flexibility in a compact form factor.
Standard features include a built-in high-speed mini-DIN port for programming and HMI connection. It also supports advanced motion control features, including built-in high-speed counters and pulse output functions. With its robust instruction set, including floating-point math and PID control, the FX3U-128MR/ES-A is a versatile solution for food processing, textile machinery, and water treatment systems.
