Product Description:

The 3BP151.4 backplane belongs to the System 2005 Controllers series produced by B & R Automation. Designed for cabinet installation, it forms the mechanical and electrical backbone that links CPU, power supply, and I/O modules, enabling centralized control of machinery and production cells. By providing a standardized slot layout, it allows packaging of logic, motion, and field-bus interfaces in a single DIN-rail segment, simplifying machine-level automation tasks such as sequence control, analog monitoring, and discrete safety.

Mechanically, the backplane occupies a depth of 23 mm, stands 165 mm high, and stretches 480 mm across the rail, so panel designers can predict enclosure space with millimeter accuracy. It offers 12 dedicated slots; internal bus conductors distribute logic and supply lines to each position, eliminating individual jumpers. Mounting follows the DIN EN 50022 (35 × 7.5 mm) standard, permitting direct latch-on to common industrial rails. With this geometry the assembly still leaves a side clearance of 20 mm for air movement and wiring. Expansion provisions allow one power module and ten additional I/O cards, matching the main module capacity stated for the platform.

Environmental limits align with control-cabinet use. The board maintains full function between 0 to 60 °C and in ambient humidity from 5 to 95 %, so it can sit near heat-generating drives without condensation risk. A housing rating of IP20 confirms that only tools are needed for safe servicing when the cabinet door is closed. System scalability is aided by an expansion capacity of 1 power supply + 10 I/O, while the main module row supports the same mix for CPU-side configurations. These figures let engineers balance channel count and power distribution without exceeding thermal or bus limits.
