FX5U-80MR/DS - Mitsubishi Programmable Controllers Melsec

The Mitsubishi FX5U-80MR/DS is a powerful Programmable Logic Controller (PLC) designed for scalable, high-speed industrial automation. It operates on a stable 24V DC power supply and consumes just 45W, making it energy-efficient for continuous operations. Equipped with 40 integrated digital inputs, 40 relay outputs, and 2 analog inputs, it provides versatile connectivity for both logic and analog control tasks.

This PLC features 64K STEPS of FLASH-based program memory, supporting extensive logic development and quick reprogramming in the field. Its cycle time of 34 nanoseconds for LD and MOV instructions makes it one of the fastest in its class, ensuring precise and timely execution in mission-critical systems. The controller can manage up to 256 local I/O points and extend up to 512 local + remote I/O points, allowing effortless expansion as process complexity grows.

Integrated Ethernet and RS-485 ports support seamless communication with SCADA systems, HMIs, and third-party industrial devices. The model is built to operate reliably up to 55°C and is protected by an IP10-rated enclosure. Its compact form factor (285 mm width, 83 mm depth, and 90 mm height) and 1.2 kg weight allow easy mounting in tight panels.

Certified with CE, UL/cUL, and UKCA standards and shipping approvals from organizations such as ABS, DNV GL, BV, NK, LR, KR, and RINA, the FX5U-80MR/DS meets international compliance demands. Widely used in automation systems across India, this Mitsubishi PLC is trusted for its reliability, flexibility, and long-term performance.
