The Mitsubishi FX3U-48MT/ES is a PLC expansion module providing 48 I/O points for the FX3U series. It uses transistor outputs (sink/source) and expands the digital I/O capacity of an FX3U CPU in a control panel.
This part is classified as mature in its lifecycle, meaning it remains available through distribution but is not the current-generation product. For new designs, consider the FX5UJ-24MT/ESS if a smaller 24 I/O count suits the application and forward compatibility with the FX5 series is desired. The FX3U-48MT/ES remains a valid replacement for existing FX3U-based installations.
