X20BM31
The B & R Automation X20BM31 base module is a versatile member of the X20 Fieldbus Input Output Modules series, designed to facilitate reliable interconnection and power distribution for double-width X20 I/O units. As part of the B & R Automation family, the X20BM31 offers an En 60529 Protection rating of IP20 to guard against solid objects and provide safety in industrial settings. It features integrated multi-power allocation capabilities, enabling separate voltage domains for upstream bus power and downstream I/O supply. The module consumes only 0.13 W on the bus, minimizing system load while ensuring robust communication across the fieldbus network. A Gost-r Certification: Yes further endorses its compliance with relevant Russian standards for industrial equipment.
Featuring a solid mechanical and thermal design, the X20BM31 supports an Operating Temperature (horizontal Installation) from -25 to 60 degrees C and an Operating Temperature (vertical Installation) from -25 to 50 degrees C, ensuring stable operation in both orientations. The module’s physical spacing requirement of 25+0.2 mm simplifies panel layout and heat management when installed alongside other X20 units. During transport and storage, it withstands a broad Transport Temperature and Storage Temperature of -40 to 85 degrees C, safeguarding electronics against thermal shock. Relative humidity tolerance includes up to 100% RH, condensing with protective coating during operation and 5 to 95% RH, non-condensing during transport, making it suitable for humid or condensation-prone environments.
Operational resilience is enhanced by its IP20 enclosure, which resists ingress by fingers and small objects while providing basic protection in controlled industrial areas. With a compact design weight and minimal power draw, the module reduces energy footprints in large I/O installations. The dual humidity ratings—condensing during run-time and non-condensing for shipment—ensure that moisture does not jeopardize module functionality or long-term reliability. The X20BM31’s broad certification and environmental tolerances support uninterrupted automation performance across diverse manufacturing and process control applications.
System integrators will appreciate the X20BM31’s plug-and-play compatibility with existing X20 backplanes and fieldbus masters, simplifying rack assembly and commissioning. Its multi-power allocation feature permits independent 24 VDC I/O supply rails (sourced from the bus module), enabling mixed analog and digital modules to operate at tailored voltage levels without external splitters. Target applications include factory automation, process control cabinets, material handling systems, and any industrial control scenario requiring flexible I/O density and robust environmental immunity.
