Product Description

MITSUBISHI FX3U-128MR/ES-A PLC Product Introduction (ECER Standard, English Only)

1. Product Overview

FX3U-128MR/ES-A is high I/O density CPU base unit of Mitsubishi MELSEC-F FX3U PLC series, designed for medium-scale sequential automation control. It adopts AC 100–240V universal power supply, configured with 64-point DC24V opto-coupler isolated digital inputs and 64-point mechanical relay outputs, reaching total 128 built-in I/O terminals. The unit collects field sensor, proximity switch and limit signal, executes compiled logic program to control solenoid valves, contactors, indicator lights and various low-power actuators. Supporting FX3U full-series extension modules including digital I/O, analog conversion, temperature detection and special positioning modules, it expands control capacity to satisfy complicated production line and multi-station equipment control demands.

2. Core Advantages & Key Features

  • High-density I/O Layout: 128 onboard I/O reduces external expansion usage, optimizes electrical cabinet space arrangement for medium automation equipment.
  • Universal Relay Output: Mechanical relay contact supports AC/DC mixed load driving, no extra intermediate relay required for conventional switching control, wide voltage adaptability for on-site loads.
  • Powerful Operation Performance: 0.065μs per basic instruction, maximum 64K-step program memory with battery backup to preserve program and internal data after power outage.
  • Flexible Expansion Function: Max local extended I/O up to 256 points; total system I/O expands to 384 points via CC-Link remote bus, compatible with all FX3U dedicated special modules.
  • Rich Communication Expandability: Standard onboard RS422 programming port; optional RS485/RS232 communication boards to realize Modbus RTU, CC-Link and other mainstream industrial bus connection.
  • Wide-range AC Power Input: AC100~240V wide voltage design effectively resists industrial grid voltage fluctuation, equipped with built-in overcurrent and short-circuit protection.
  • International Certification & ECER Compliance: Certified with CE and UL, conforming to EN61131-2 and EN61000 EMC standards, meets EU ECER safety requirements for machinery export and whole-machine certification.
  • Standard DIN Rail Mount: 35mm DIN rail installation, detachable screw terminal block for convenient field wiring and daily maintenance.
