With 14 inputs and 10 relay outputs on board, the Mitsubishi FX5UJ-24MR/ES is one of the standard FX5UJ base units used in machine building and panel retrofits.
When a compact PLC fails, the quickest repair is an identical base unit: the terminal layout, expansion bus and program stay the same, so the machine can be back in production after a project download.

Compatibility and replacement
Replace with the identical model FX5UJ-24MR/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.
