Allen-Bradley 1756-PBR2 Redundant Power Supply Bundle – ControlLogix
When a power supply fails in a live production environment, the consequences are immediate and severe: unplanned downtime, halted assembly lines, compromised batch processes, and in critical infrastructure, potential safety incidents. In high-availability industrial systems, a single point of power failure is simply not acceptable. The Allen-Bradley 1756-PBR2 eliminates that vulnerability by enabling true redundant power delivery within the ControlLogix chassis — ensuring your automation system keeps running even when one supply is lost.
The 1756-PBR2 is a Power Supply Bundle specifically engineered for the Allen-Bradley ControlLogix 1756 platform — Rockwell Automation’s flagship large-scale PLC architecture trusted in mission-critical applications across oil & gas, automotive, water treatment, and advanced manufacturing worldwide. As part of the ControlLogix family, the 1756-PBR2 integrates seamlessly with the 1756 chassis backplane, providing the redundant power infrastructure that enterprise-grade automation demands.
