The Mitsubishi FX3S-30MR/DS and FX3S-30MT/DS are high-performance PLC controller modules tailored for compact automation systems. These modules integrate 30 I/O points, offering either relay (MR) for high-current switching or transistor (MT) for high-speed output. With a rich set of internal relays, timers, counters, and data registers, the FX3S series delivers reliable logic control for machinery, packaging, and process applications. Below is the detailed technical specification.
