ControlLogix Redundant Power Supplies
To build a redundant power supply system, you need:

two redundant power supplies (both 1756-PA75R or 1756-PB75R)one 1756-PSCA2 chassis adapter module, which funnels power from the redundant power supplies to the single power connector on the ControlLogix series B chassis backplanetwo 1756-CPR2 cables to connect the power supplies to the 1756-PSCA2 chassis adapter moduleuser-supplied annuniciator wiring to connect the power supplies to the input modules, as needed

The 1756-PSCA2 chassis adapter module is a passive device that funnels power from the redundant power supplies to the single power connector on the ControlLogix series B chassis backplane.
