Allen Bradley ControlLogix Power Supplies

Power Supplies

Available to provide 1.2V, 3.3 V, 5 V, and 24 V DC power. Requires one power supply per chassis for standard systems, or a power supply bundle can be selected for redundant systems.

Your options include one power supply for each chassis in a standard system or a power supply bundle in a redundant system. Power supplies mount on the left end of the chassis and plug directly into the backplane. Redundant power supplies provide additional uptime protection for ControlLogix systems used in critical applications. Consult the following table for the appropriate power supply for your system.
