Product Description:

The 3BP151.41 is a modular controller base produced by B & R Automation for the System 2005 Controllers series. It provides the mechanical and electrical backbone for CPU, power supply, and I/O cards used in automated machinery. By combining logic processing with local and remote signal conditioning, the unit acts as the central node that sequences motion, monitors process variables, and exchanges data with higher-level networks across a plant floor. Its design targets compact control cabinets where space efficiency and organized module layout are important. This arrangement supports centralized control while allowing multiple machine functions to be handled from one platform.

The chassis is 480 mm wide, 165 mm tall, and 23 mm deep, so it occupies minimal panel depth while still exposing the card connectors across the front. The controller offers 12 slots, arranged on a main backplane for the power supply, CPU, and system or I/O modules; an adjacent expansion rail can carry an additional power supply and up to ten I/O units when a larger node count is needed. Its shallow profile helps when cabinet space is limited by wire ducts, door hardware, or neighboring power components. An IP20 rating means the assembly is protected against finger contact and settled dust, but it must be mounted inside a closed enclosure with controlled airflow.

Control data is preserved during power loss because a backup battery is fitted from the factory. The cell uses Lithium chemistry, stores 950 mAh of charge at 3 V, and can remain in storage for three years at 30 °C without falling below its minimum capacity. Operating limits are suited to standard control cabinets, and the electronics remain functional from 0 °C up to 60 °C in ambient humidity between 5 % and 95 % non-condensing. This allows the System 2005 controller to serve packaging lines, conveyors, and similar equipment that experience routine temperature changes while staying within the stated operating limits.
