ABB BB512 3BUR980001R0001 Bus Backplane Module

Product Description

The BB512 3BUR980001R0001 is a rack-mounted bus backplane engineered for ABB Advant OCS and AC 400 control platforms. It serves as the core mechanical carrier and electrical interconnection layer within AC 400 controller racks, enabling secure installation and synchronized communication between control, I/O, and interface modules.

Designed for continuous operation in demanding industrial environments, this backplane provides stable power distribution and deterministic bus signaling across all installed modules. Its 18SU form factor supports scalable system layouts while maintaining consistent electrical performance over long service lifecycles.

System Compatibility and Architecture

The BB512 (3BUR980001R0001) integrates natively with ABB’s Advant OCS architecture and MOD 300–based AC 400 controllers. It supports central processing units, distributed I/O assemblies, and communication interfaces, forming the physical and electrical foundation of the controller rack.

The backplane aligns with ABB’s modular design philosophy, allowing system expansion, maintenance, and modernization without redesigning the rack infrastructure.
