B&R Industrial Automation X20PS3300 Power Supply

X20PS3300 is a 24 VDC power supply module for B&R’s X20 Fieldbus I/O system, designed to feed the X2X Link power bus and the internal I/O supply from a compact, on‑board source. It includes reverse polarity protection on its 24 V input and status indicators to signal overload or normal operating state, helping technicians quickly diagnose power issues on the line. The module is intended to be used as part of the X20 backplane, delivering power to X2X Link devices while maintaining isolation between the X2X Link input and the power output, which enhances fault containment for the control logic and field I/O. Typical input voltage is 24 VDC with a tolerance of -15% to +20%, aligning with the rugged, industrial requirements of X20 installations. As a member of the X20 Power Supply family, the X20PS3300 supports the X2X Link architecture by supplying power to the X2X Link bus and to connected I/O modules, enabling a streamlined, space‑saving approach to 24 V control circuits in automation cells, packaging lines, and other manufacturing environments that rely on B&R’s X20 ecosystem.
