Allen-Bradley 1756-CPR2 is a ControlLogix redundant power supply cable that links the redundant power supply to the 1756-PCSA2 chassis adapter in a ControlLogix rack. It is 0.91 m (3 ft) long, providing a dedicated, short-length connection designed for reliable power redundancy in 1756 chassis systems. This cable is employed when configuring a redundant power path for ControlLogix backplanes, ensuring continuity of operation by allowing a second power source to back up the primary supply.
