B&R X20PS2100 Power Supply Module

The Bernecker + Rainer X20PS2100 is a 24 VDC power supply module designed to provide the internal I/O power rail for the X20 I/O system. It accepts 24 VDC input with a tolerance of -15% to +20% and delivers a nominal 24 VDC output to the I/O power bus, with a permissible contact load of 10 A. A line fuse is required (max. 10 A slow-blow) and reverse polarity protection is not provided. The I/O supply is not isolated from the I/O power supply, and the module carries IP20 protection with mounting support for both horizontal and vertical orientations. Operating conditions include 0 to 2000 m elevation without derating, with derating above 2000 m (ambient temperature decreases by 0.5°C per 100 m). Certifications include CE, UKCA, and UL/cULus (E115267), along with ATEX/IECEx approvals for hazardous locations (Zone 2, II 3G Ex nA nC IIA T5 Gc). The X20PS2100 is part of B&R’s X20 power-supply family, and its device identity is reflected in the X20 product ecosystem’s power architecture for compact, integrated panel installations.
