Mitsubishi Electric FX5U-32MT/ESS MELSEC iQ-F Series CPU Unit

Description

System designers requiring high-performance industrial control utilize the FX5U-32MT/ESS as a central processing hub within the MELSEC iQ-F automation platform. This programmable logic controller (PLC) CPU module features integrated high-speed analog and digital processing capabilities, delivering execution speeds suited for complex motion control, process synchronization, and machine automation.

The unit integrates 16 digital inputs (24 V DC, sink/source configurable) and 16 transistor outputs (source type), permitting direct interfacing with standard sensors and actuators. It operates on a universal AC power supply (100 to 240 V AC) and provides built-in Ethernet and RS-485 communication interfaces to ensure seamless networking across industrial systems without requiring additional communication cards.

Features

• Built-in Ethernet port for network configuration, program monitoring, and Modbus TCP communication.
• Integrated RS-485 serial port supporting Modbus RTU and MELSOFT protocols.
• Dedicated SD memory card slot for data logging, diagnostic storage, and program transfer.
• Support for up to 4 channels of 200 kHz high-speed pulse output for precise positioning control.
• Built-in analog I/O featuring 2 channels of analog input (0 to 10 V DC) and 1 channel of analog output (0 to 10 V DC).
• Expandable system configuration through backplane expansion modules and local I/O cards.

Applications

• Packaging and labeling machinery
• Material handling and conveyor systems
• Pumping, water treatment, and fluid control systems
• HVAC and building environmental automation
• Assembly lines and testing equipment

Technical Specifications

Installation Guidelines

• Mount the unit horizontally on a standard 35mm DIN rail or attach it directly to a flat panel using the integrated mounting screw holes.
• Maintain a minimum of 50 mm clearance above, below, and on both sides of the CPU module to facilitate adequate convection cooling.
• Connect the protective ground terminal (Class D grounding, 100 Ohm or less resistance) using a dedicated ground wire with a cross-sectional area of at least 2 mm².
• Separate all low-voltage signal lines (I/O, analog, and network communication cables) from main power lines or high-voltage wiring to minimize electromagnetic interference.

Compliance and Certifications

• CE (EMC Directive, Low Voltage Directive)
• UL / cUL Listed
• KC Certification
