Specification

SEODescription

The Mitsubishi FX3S-20MT/DSS PLC is a compact and cost-effective controller designed for small-scale automation applications. This FX3S-20MT/DSS Controller features 12 digital inputs and 8 transistor outputs (sink/source type), enabling direct integration with sensors, switches, and actuators. It supports connection to up to two expansion modules (such as FX3S extension blocks or communication adapters) for I/O expansion or communication enhancements. The unit operates on a wide AC power range (100-240V AC) and withstands industrial temperatures from 0°C to 55°C. With built-in RS-422 and USB ports, it supports programming via Mitsubishi's GX Works3 software and basic communication protocols like Modbus RTU. Ideal for manufacturing, packaging, and material handling industries, the FX3S-20MT/DSS offers simplified programming and reliable performance. However, its limited memory capacity and expansion capabilities make it unsuitable for complex or large-scale systems.
