Specification

SEODescription

The Mitsubishi FX5UJ-40MT/ESS PLC is a compact automation controller with 40 integrated I/O points (24 digital inputs and 16 transistor outputs), designed for small to mid-scale industrial applications. It supports direct connection of up to 4 expansion modules, enabling flexible system scaling. Equipped with built-in Ethernet, RS-485, and USB ports, it facilitates seamless communication via protocols like Modbus/TCP and SLMP. Operating at 24V DC within 0–55°C, this PLC suits industries like packaging, material handling, and assembly lines. Its advantages include high-speed processing (1ns/instruction), energy efficiency, and user-friendly programming via GX Works3. However, limited analog I/O integration and moderate network scalability may require additional modules for complex setups.
