1769-PB4: Compact I/O Power Supply 24VDC Input
The 1769-PB4 is specified as Compact I/O Power Supply 24VDC Input. Where this variant differs from others in its family is the configuration listed below — confirm it against the unit being replaced.
What separates this variant from its siblings is compact i/o power supply 24vdc input. A power supply or battery in a controller rack is sized against the backplane budget, not in isolation. compact i/o power supply 24vdc input 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 the configuration shown in the specification table against the rack's requirement prevents a supply that fits the slot but cannot hold the load.
