B&R Industrial Automation X20DO2649 Digital Output Module

The B&R X20DO2649 is a dual-relay digital output module for the X20 I/O system, delivering two isolated relay outputs with changeover contacts for switching AC mains and DC loads. Each channel provides 30 V DC / 240 V AC switching capability, with a 5 A rating per output, and outputs are isolated from one another (single-channel isolation) to protect the controller from load transients. The module mounts in the X20 bus and draws about 0.45 W from the backplane, enabling compact power budgeting in automated machines. It carries multiple safety and compliance marks, including CE, UKCA, UL/cULus, and ATEX Zone 2 approvals (II 3G Ex nA nC IIA T5 Gc), and is IP20 protected with Ta per the X20 documentation. The X20DO2649 is identified on the X20 system with the ID code 0x20DA for straightforward integration with a B&R controller, and its two-relay, changeover-output design is well-suited for applications such as energizing solenoids, valves, indicators, and other 24 VDC or 240 VAC loads in industrial equipment. This module is part of the X20 family, combining a compact form factor, robust isolation, and broad safety certifications to support reliable automation in harsh environments.
