Product Description:
The 2BP110.3 is a base plate module produced by B & R Automation for the System 2010 Controllers series. As the structural backbone of a controller stack, it provides mechanical support and backplane wiring so CPU, power supply, and I/O cards can share power and data lines without separate cabling. Its role in industrial automation is to simplify the assembly of small and medium control systems by providing one platform that aligns modules, distributes the system bus, and ensures correct grounding through the mounting rail. This arrangement reduces loose interconnect wiring inside the cabinet and keeps module placement organized during installation.
Communication across the backplane is handled by the internal System bus. The plate already carries bus termination, so no extra resistor plug is needed at the end of a segment. The base plate provides capacity for 4 system modules, which is enough room for a CPU, a power supply, and two function cards on one carrier. This layout supports compact controller assemblies where several core functions must be mounted on a single carrier. Cabinet depth is conserved because the assembly extends only 20 mm from the rail, and its face width of 160 mm leaves space for adjacent drives or terminal strips.
The frame rises to 285 mm, allowing space above the assembly for nearby cable routing or power rails. It snaps onto a 35 × 7.5 mm steel rail, and the clamp profile matches DIN IEC 50022, so it fits standard control cabinets without drilling auxiliary holes. Because it is classified as a Main base plate, it serves as the first element in a System 2010 rack and provides the initial power feed. Its molded keying helps subsequent modules seat correctly and reduces the chance of misalignment at the system connectors.
