Mitsubishi Electric FX3GE-24MR/ES MELSEC FX3GE PLC CPU

Description

Designed to deliver high-performance automation in a compact footprint, the FX3GE-24MR/ES central processing unit integrates built-in analog inputs/outputs and dual communication ports directly into a single MELSEC FX series PLC platform. This controller combines the proven architecture of the FX3G series with integrated Ethernet and analog functionalities, eliminating the need for additional expansion adapters in basic networking and process control scenarios.

The FX3GE-24MR/ES features 24 integrated I/O points, configured as 14 digital inputs and 10 relay outputs. It serves as a highly efficient control node for manufacturing, water treatment, and specialized machinery, providing robust processing speed, built-in USB and RS-422 ports, and seamless connection to supervisory control systems via its integrated RJ45 Ethernet interface.

Features

• Integrated communication capabilities featuring built-in Ethernet (10BASE-T/100BASE-TX), USB (Mini-B), and RS-422 ports.
• Built-in analog capability with 2 channels of analog input and 1 channel of analog output.
• Relay outputs rated up to 2 A per point, suitable for switching direct loads without additional coupling relays.
• Robust program memory capacity supporting complex sequential logic, timing, and calculation blocks.
• Expandability via FX3 series expansion boards, special adapters, and functional extension blocks.
• LED status indicators on the front panel for immediate diagnostics of power, run, error, and I/O states.

Applications

• Industrial pump stations and water treatment operations.
• Packaging, labeling, and filling machinery.
• Material handling systems and conveyor controls.
• HVAC and environmental monitoring systems.
• Distributed control nodes within larger factory-wide Ethernet networks.

Installation Guidelines

• Mounting: Install on a standard 35 mm DIN rail or utilize direct screw mounting in a secure control cabinet.
• Spacing: Maintain at least 50 mm of ventilation clearance above and below the CPU to ensure adequate heat dissipation.
• Grounding: Ensure a dedicated Class D grounding connection (grounding resistance of 100 ohms or less) using a minimum 2 mm² wire.
• Wiring: Do not route input/output cables in the same conduit or close to high-voltage power lines to prevent electromagnetic interference.
