MITSUBISHI FX3U-128MR/ES Used Working PLC Controller

Product Overview

The Mitsubishi FX3U-128MR/ES is the high-performance, top-of-the-line base unit in the MELSEC FX3U series. As the third generation of Mitsubishi's compact PLC family, the FX3U-128MR/ES provides an impressive 128 integrated I/O points (64 inputs and 64 relay outputs). This "All-in-One" controller is designed for high-speed, complex automation tasks, featuring significantly faster processing speeds and expanded memory compared to its predecessors. As a Used Working unit, it is a robust solution for large-scale industrial applications, such as high-speed packaging, multi-axis motion control, and extensive factory automation.

Key Features

• Maximum Integrated I/O: Features 64 Digital Inputs (24V DC, Sink/Source) and 64 Relay Outputs, offering the highest density in a single FX-series chassis.
• Extreme Processing Speed: Boasts a basic instruction execution time of just 0.065 µs, making it suitable for the most demanding real-time control applications.
• Large Program Memory: Equipped with 64,000 steps of internal RAM memory, allowing for sophisticated and lengthy logic programs.
• High-Speed Counters: Includes up to 8 channels of high-speed pulse inputs (up to 100 kHz), ideal for high-resolution encoder feedback.
• Flexible Relay Outputs: The 64 relays support both 24V DC and 240V AC switching with a capacity of 2A per point, providing versatile control for solenoids and contactors.
• Enhanced Expandability: Supports a wide range of expansion via the high-speed bus, including analog I/O, temperature control, and specialized communication modules (Ethernet, CC-Link).
• Global Standard Power Supply: The "ES" designation indicates a wide-range 100-240V AC power supply, compliant with international safety standards.

Item Condition (Used Working)

• Functional Status: Used Working. This unit has been professionally bench-tested. The internal "RUN" mode has been verified, and communication via the programming port is stable.
• Physical State: Clean industrial condition. All terminal blocks and screw connectors are intact. The plastic housing and DIN rail clips show standard signs of industrial use but no structural damage.
• Technical Integrity: The internal battery has been checked for voltage levels. Program memory has been cleared. All 128 I/O status LEDs have been verified for correct operation.
• Note: Professional installation is recommended. This unit is the largest in the FX3U family; ensure your control cabinet has sufficient space and ventilation for its footprint.
