Specification

SEODescription

The FX5S-40MT/DSS is a compact programmable logic controller (PLC) from Mitsubishi Electric's FX5S series, designed for small-scale automation. This FX5S-40MT model integrates 24 digital inputs and 16 transistor outputs, totaling 40 I/O points, and supports direct connection of up to 8 expansion modules for flexibility. The FX5S/DSS-Controller features built-in RS-485, USB, and Ethernet ports, enabling seamless communication with HMI, sensors, and SCADA systems. Operating within 24V DC power and a temperature range of 0–55°C, it is ideal for manufacturing, packaging, and assembly lines. Key advantages include high-speed processing, compact design, and intuitive programming via GX Works3. However, limited analog I/O compatibility and module expansion capacity may restrict complex applications. Its robust performance and cost-effectiveness make it a popular choice for basic industrial automation tasks.
