Choosing a Power Supply
This section contains information for selecting a power supply for applications
using a 1764-28BXB base unit. Use the tables in Appendix F to calculate the total
power (Watts) consumed by the system. With that information, use the graphs
below to chose a power supply. You can use either current or power, depending on
how the power supply is rated.
