The Mitsubishi Electric FX3U-64MT/ES is a MELSEC-F FX3U PLC CPU with 32 digital inputs and 32 transistor outputs (Sink), powered from 100-240 V AC.
It is programmed with Mitsubishi GX Works2 (or GX Works3 for conversion projects). The program is stored in the CPU, so a replacement unit only needs the project file to be downloaded again.
Mitsubishi Electric lists the FX3U-64MT/ES as discontinued (EOL 19.06.2026, last time buy 31.01.2027). Spares for installed machines remain in demand; ask us for stock or for the current successor before you plan a retrofit.

Compatibility and replacement
Replace with the identical model FX3U-64MT/ES to keep the same terminal layout and power supply (100-240 V AC). Check the suffix carefully: R = relay outputs, T = transistor outputs, ES/ESS and DS/DSS set the supply and sink/source logic.
Back up the PLC program before removing the old unit, and download it to the new CPU with the same software version or newer.
