The Mitsubishi FX3S-20MT/DSS PLC is a programmable logic controller designed for compact industrial automation systems. This Mitsubishi PLC uses a 24V DC power supply and features 16K steps EEPROM program memory for stable logic execution. It supports 12 digital inputs and 8 transistor outputs with source logic. The FX3S-20MT/DSS PLC belongs to the FX Series and is applied in controlled automation environments.
In industrial applications, the Mitsubishi FX3S-20MT/DSS PLC is used in conveyors, small packaging machines, basic assembly stations, and control panels. Transistor outputs enable consistent switching for sensors and actuators, while fixed I/O architecture supports predictable system behavior. Defined instruction cycle times help maintain stable operation in continuous and intermittent production processes.
The Mitsubishi FX3S-20MT/DSS PLC combines compact size, low power consumption, and transistor-based outputs in a fixed I/O controller format. As part of Mitsubishi’s FX Series PLC portfolio, it aligns with established industrial standards and certifications. This PLC is suitable for long-term industrial use where space efficiency, electrical reliability, and consistent automation control are required.
