The Mitsubishi Electric FX5U-80MR/ES is an 80-point CPU module in the MELSEC iQ-F Series, designed for industrial automation systems requiring a larger number of integrated I/O points. It combines 40 digital inputs and 40 relay outputs in a single PLC CPU, providing a practical control solution for sensors, switches, contactors, valves, actuators, and other industrial devices. Its 100 to 240 V AC power supply and 24 V DC sink/source input configuration allow it to be integrated into a wide range of industrial control panels and machine automation systems.
A major feature of the FX5U-80MR/ES is the range of functions built directly into the CPU. It provides 2 built-in analog input channels and 1 analog output channel, together with high-speed counter functionality supporting up to 8 channels at 200 kHz. The CPU also includes built-in Ethernet and RS-485 communication ports for connecting compatible automation equipment and industrial networks. Mitsubishi Electric specifies a 34 ns LD instruction processing speed, supporting fast sequence control in demanding applications.
The FX5U-80MR/ES can be used in production machinery, packaging equipment, conveyor systems, material handling, machine control, process equipment, and general factory automation applications. Its 40 relay outputs provide flexible switching capabilities for a variety of industrial loads within the specified electrical ratings. Mitsubishi Electric currently lists the FX5U-80MR/ES as an on-sale MELSEC iQ-F CPU module. For replacement or maintenance applications, users should verify the exact model number, power supply, I/O configuration, wiring requirements, and compatibility with the existing Mitsubishi Electric system before installation.
