Product Description

The X20BM21 is a noteworthy bus module intended for segmenting voltage groups in an industrial system. Specifically, the X20BM21 is compatible with X20's double-width I/O modules. For this bus module, the I/O power supply is internally isolated on the left side, allowing other parts of the bus module to be used for other purposes. B&R Automation's rationale for manufacturing this bus module is to create a product capable of interconnecting several modules and devices, each having their own power and voltage requirements. In itself, the X20BM21 consumes only 0.13 watts of power and requires 24 VDC for its power supply.

Like other B&R Automation bus unit modules, the X20BM21 incorporates standard DIN rail mounting. It also supports vertical and horizontal installations, making it an ideal module for almost all industrial systems requiring a compact and versatile bus module. The advantage of using B&R's X20 devices is that most of the products under this series make up a modular system. With a modular system, multiple I/O devices can be connected together depending on the demands of the system. The bus module serves as the physical and electrical platform that connects these modular devices together, simplifying wiring and system design.

As a compact bus module, the X20BM21 requires only a spacing of 25 millimeters from other adjacent modules. It features a protection grade of IP20 and operates at a maximum temperature of 50 degrees (vertically mounted) or 60 degrees (horizontally mounted). The X20BM21 experiences no derating even when installed at high installation levels. For this module, higher installation levels only affect the ambient temperature.
