B&R Industrial Automation GmbH X20BM11 Bus Monitor Module

X20BM11 is a B&R X20 bus module with a dedicated power-bus connection for the X20 I/O system, serving as a bus monitor that provides an internal 24 VDC I/O supply to connected modules. The module draws only about 0.13 W from the backplane and delivers a nominal 24 VDC I/O supply with a 10 A contact load rating. It measures 100 mm in length, 60 mm in width, and 10 mm in height (approximately 0.05 kg), offers IP20 protection, and supports horizontal mounting from -25 to 60°C or vertical mounting from -25 to 50°C, with altitude tolerance from 0 to 2000 m and derating above that. The X20BM11 carries standard industrial certifications including CE and UL/cULus, and it slots into the X20 backplane to enable reliable 24 V I/O power distribution across the X20 modular system.
