System Using a 1769-PB2
To validate your system, the total 5V dc current and 24V dc current consumed
must be considered. The I/O modules must be distributed, such that the current
consumed from the left
or right side of the power supply never exceeds 2A at 5V dc
and 1.0A at 24V dc. Use the current graph below to determine if the power supply
loading in your system is within the allowable range.
