Product Description:

The 3BP150.41 controller rack is produced by B&R Automation as part of the System 2005 Controllers series. It provides the structural and electrical backplane that supports the CPU, power supply, and fieldbus cards used to coordinate machine-level control tasks across an automated line. The rack also distributes internal connections between installed modules, so the controller assembly can be organized on a single compact frame rather than through scattered point-to-point wiring. Its DIN-mountable format helps the unit fit neatly inside industrial control cabinets while keeping the module layout easy to follow.

A backup battery is included, and its 950 mAh capacity with a 3 V output provides retention power when input power is removed. The rack contains 15 card slots, and the integrated system bus can address up to 13 I/O modules on the expansion rail while the remaining positions are reserved for the processor and supply hardware. Thermal endurance reaches 60 °C, and the unit can operate in relative humidity from 5% to 95% when condensation is avoided. This range supports use near switchgear, drives, and other equipment that can raise cabinet temperature during normal operation.

The cabinet layout is supported by a width of 600 mm and a height of 165 mm, while the 23 mm depth allows shallow installation without reducing door clearance. A minimum operating temperature of 0 °C allows cold starts in unheated equipment rooms as long as moisture does not condense on the rack or modules. The enclosure carries an IP20 protection rating, which provides finger-safe access but still requires installation inside a closed cabinet. This layout leaves room for adjacent wiring ducts and power components, and it helps the controller fit compact packaging lines, material handling systems, and small machining stations.
