Product Description – Schneider STBXSP3010 Power Supply Module

The Schneider STBXSP3010 is a robust Power Supply Module (PSM) within the Modicon Advantys STB distributed I/O range. It provides regulated 24 V DC field power and 5 V DC logic power to STB islands, ensuring reliable operation of all connected input and output modules. Moreover, it offers galvanic isolation between input and output circuits, protecting both the STB backplane and downstream field devices from electrical faults. Therefore, this module is essential for industrial automation, machine control, and process monitoring applications.

Its compact DIN-rail design allows easy integration into STB islands, supporting hot-swappable installation for minimal downtime. In addition, LED indicators provide instant diagnostics of logic and field power status, helping technicians quickly identify and resolve any issues. Its durable construction and IP20 protection rating make it suitable for a wide range of industrial environments.
