1756-PB72: ControlLogix DC Power Supply 18 32VDC
The 1756-PB72 is the ControlLogix DC Power Supply 18 32VDC covered on this page. The attribute that decides whether it fits the existing installation without modification is 24 Volts DC.
This configuration's controllogix dc power supply 18 32vdc is the attribute that drives the replacement decision. A power supply or battery in a controller rack is sized against the backplane budget, not in isolation. controllogix dc power supply 18 32vdc is whether the unit delivers the voltage and current the rack draws at full load, and whether the battery holds programme and configuration through a power loss. Checking 24 Volts DC against the rack's requirement prevents a supply that fits the slot but cannot hold the load.
