1756-PA72K: ControlLogix AC Power Supply Module
The 1756-PA72K is the ControlLogix AC Power Supply Module covered on this page. The attribute that decides whether it fits the existing installation without modification is 120-240 Volts AC.
What separates this variant from its siblings is controllogix ac power supply module. A power supply or battery in a controller rack is sized against the backplane budget, not in isolation. controllogix ac power supply module 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 120-240 Volts AC against the rack's requirement prevents a supply that fits the slot but cannot hold the load.
