The Mitsubishi FX5UC-64MT/DSS is a 64-point programmable logic controller with transistor outputs, classed as a PLC main unit in the FX5UC compact series and catalogued under PLC Expansion Modules on the broader PLCs & HMIs line. It is specified for comprehensive industrial automation and multi-axis control duty, which means the CPU, onboard I/O and high-speed counter/transistor output channels are bundled into one unit rather than split across a base plus discrete expansion racks.
Spec recap for the specifier
Single CPU/IO bundle on this listing — no MODBUS bridge, no fieldbus gateway, no analog option card is described in the available row set, so any comms expansion or analog channels come from add-on modules rather than from the base unit itself.
