Allen-Bradley CompactLogix 5480

22 Rockwell Automation Publication 5069-UM002A-EN-P - January 2019
Chapter 1 CompactLogix 5480 System
• The total continuous current draw across the MOD power bus must not
be more than 10 A, max, at 18...32V DC.
• We recommend that you use an external power supply that is adequately
sized for the total MOD power bus current draw in the system.
You must consider inrush current requirements when you calculate the
total MOD power bus current draw in the system.
Figure 4 - External Power Supply Provides MOD Power
IMPORTANT The controller itself draws 4 A at 18…32V DC and passes 6 A at
18…32V DC to the local I/O modules. This is the case if an external
power supply is connected to one set of MOD power RTB terminals
as shown in
Figure 4.
Remember, MOD power usage includes the total power that the
controller and local Compact 5000 I/O modules use. If you connect
external power to both sets of MOD power RTB terminals, however,
the local Compact 5000 I/O modules can draw a maximum of 10 A in
addition to the current that the controller draws.
