Specification

SEODescription

The Mitsubishi FX3S-20MR/DS PLC is a compact programmable logic controller designed for small-scale automation applications. It features 12 digital inputs and 8 relay outputs (FX3S-20MR/DS Relay Output), supporting direct control of AC/DC loads. The unit operates on a 24V DC power supply (FX3S-20MR/DS DC Power) with a voltage range of 20.4–28.8V DC and functions reliably within 0–55°C. It supports up to 3 expansion modules for I/O or analog extensions and includes a built-in RS-422 programming port for communication with Mitsubishi’s GX Works2 software. Ideal for packaging, conveyor systems, and light machinery, its key advantages include cost-effectiveness, user-friendly programming, and a space-saving design. However, its limited memory and module expansion capacity may restrict scalability for complex projects.
