The Mitsubishi FX3S-10MR/DS and FX3S-10MT/DS are the latest additions to the MELSEC FX3S family, designed for cost-sensitive yet demanding applications. These compact PLC controllers pack a punch with 10 built-in I/O points, supporting either relay (MR) or transistor (MT) output types. With a robust instruction set and high-speed processing, the FX3S series excels in standalone machine control, packaging systems, and small conveyor lines. The model-specific suffix “/DS” indicates a DC power supply and sink/source input configuration, making it ideal for 24 VDC industrial environments. All units are 100% original and new, sourced directly from Mitsubishi’s authorized supply chain.
