Mitsubishi Electric FX3GE-40MR/ES FX3GE Series Programmable Controller

Description

Designed to meet the demands of compact yet comprehensive industrial automation systems, the FX3GE-40MR/ES main unit integrates advanced control capabilities with built-in network connectivity and analog processing. This programmable logic controller (PLC) from the Mitsubishi Electric MELSEC FX family offers 40 local I/O points in a single, space-saving chassis.

The unit features a robust relay output structure alongside 24 discrete digital inputs, operating on a standard wide-range AC power supply. Engineered for standalone machinery and distributed control systems, the FX3GE-40MR/ES includes a built-in Ethernet port and integrated analog functional channels. This eliminates the need for external analog or network adapters in standard applications, optimizing both cabinet footprint and system integration costs.

Features

• High-density local configuration with 24 integrated digital inputs and 16 electromagnetic relay outputs.
• Built-in Ethernet port for seamless network integration, programming, data monitoring, and SCADA connectivity.
• Integrated analog capability featuring 2 analog inputs and 1 analog output channel natively on the CPU board.
• Wide-range power supply compatibility, operating efficiently on standard 100-240 VAC networks.
• High-speed program execution processing to handle demanding sequence control and timing tasks.
• Expandable hardware platform supporting additional MELSEC FX series expansion boards and special function blocks.

Applications

• Packaging, labeling, and wrapping machinery.
• Water and wastewater treatment pumping systems.
• HVAC, environmental, and climate control automation.
• Material handling systems, conveyors, and sorting lines.
• Food and beverage manufacturing and process control.

Technical Specifications

Installation Guidelines

• Mount the unit on standard 35 mm DIN rail or directly to a backpanel using the integrated mounting screw holes.
• Provide a minimum clearance of 50 mm above and below the PLC to maintain proper natural convection cooling.
• Ensure class-D grounding (grounding resistance of 100 ohms or less) using a dedicated grounding wire with a minimum cross-section of 2 mm squared.
• Route low-voltage signal lines (Ethernet, analog, and digital I/O) separately from high-voltage AC power wiring to prevent electromagnetic noise coupling.
