Replacement Considerations with CompactLogix and Compact GuardLogix Systems Chapter 3
Power the Controller
There are differences in how to power the 5380 controllers versus the 5370
controllers. Table 1 0
highlights some of the power differences.
For information on how to power your system, see the
CompactLogix 5380 and Compact GuardLogix 5380 Controllers User
Manual, publication 5069-UM001
.

Power source Compact I/O power supply External power supply
Power source location Power supply that is installed in the
system
The power supply location is based on the
requirements of the modules in the
system.
Separate from the system and connected to RTBs on controller
The modules installed in the system do not impact the power supply location. Power is transferred to the
system via removable terminal blocks (RTBs) on the controller.
Power types provided System-side power only • System-side power via MOD Power RTB
• Field-side power via SA Power RTB
IMPORTANT: RTBs do not ship with the controller. The RTBs are available in kits that you must order
separately.
Kit 5069-RTB64-SCREW contains screw-type RTBs that are used for MOD power and SA power.
Kit 5069-RTB64-SPRING contains spring-type RTBs that are used for MOD power and SA power.
Current type provided AC or DC as dictated by system design • System-side power - DC only
• Field-side power - AC or DC as dictated by
system design
• System-side power - DC only
• Field-side power - DC only at the controller, AC
only through the use of a local 5069-FPD, Field
Potential Distributor module.
Special requirement • Must meet Power Supply Distance
Rating requirements
• Must track power consumption in the
local bank and on both sides of the
power supply
• Must track the system-side and field-side power consumption to properly size the external power
supplies that provide each power type.
• Must use 5069-FPD, Field Potential Distributor if SA Power consumption is exceeded before reaching
max of 31 local I/O modules.
• Must use Field Potential Distribution module to change SA Power potential between AC and DC.
