STBPDT3100K | Modicon Advantys STB Logic and Field Power

Product Description – Schneider STBPDT3100K Power Distribution Kit

The Schneider STBPDT3100K is a high-performance Power Distribution Module (PDM) within the Modicon Advantys STB distributed I/O range. It supplies regulated 5 V DC logic power and 24 V DC field power to all I/O modules within an STB island. Moreover, it provides galvanic isolation between the logic bus and field devices, ensuring reliable operation in industrial automation systems. Therefore, it is essential for process control, machine monitoring, and distributed automation applications where stable power distribution is required.

This compact DIN-rail mounted module allows hot-swappable installation, making maintenance fast and reducing downtime. In addition, LED indicators provide real-time diagnostics of logic and field power, simplifying troubleshooting and ensuring safe operation. Its durable design and IP20 protection rating make it suitable for a variety of industrial environments.
