Specification

SEODescription

The **FX3U-FLROM-64L** is a Mitsubishi-FX3U-memory expansion module designed to enhance data storage capabilities for FX3U-series PLCs. This FLROM-64L-module provides 64K steps of flash memory for reliable program and parameter storage, ensuring data retention during power loss. It connects directly to the FX3U PLC via a built-in interface, supporting seamless integration without additional hardware. While the module itself lacks direct I/O, it complements the PLC's existing inputs and outputs, enabling larger program execution. Compatible with Mitsubishi's GX Works2 software, it supports RS-422/485 and USB communication for programming and diagnostics. Operating at 24V DC within 0–55°C, it suits industrial automation, manufacturing, and machinery control. Key advantages include rugged design, high reliability, and simplified backup, though it is limited to FX3U systems and lacks standalone functionality.
