Chapter 1 CompactLogix 5480 System
Power the System
The CompactLogix 5480 controller provides power to the system as follows:
• MOD Power - System-side power that powers the CompactLogix 5480
system and lets modules transfer data and execute logic.
System-side power is connected via the MOD power RTB.
• SA Power - Field-side power that powers some Compact 5000 I/O
modules and field-side devices that are connected to them.
Field-side power is connected via the SA power RTB.
• UPS Control Signals - Control signals that let the controller execute a
controlled shutdown and save the current state of the project, if the
source of MOD power is unexpectedly lost.
UPS control signals are connected via the UPS control RTB.
