Selecting Power Supplies, Encoders, and Drives
Example of Calculations for Backplane Current Requirements
In this example, the system includes:
One seven-slot modular rack
One 1747-L543 CPU module
One 1746-IB8 DC input module with eight inputs @ +24V
One 1746-OV8 DC output module with eight outputs @ +24V
An SLC Servo Module system that contains:
SLC Servo Modules
Termination panels
Allen-Bradley 845H encoders
Fast inputs
Fast outputs
Use the table below to find the current requirements of the devices
using backplane power. Those devices that are not included in the
backplane calculations are included in the example’s user-side
calculations.
If optional processor is used:
Device +5V +24V
1746-L543 processor 1A .200A
SLC Servo Module .300A 0
1746-IB8 .040A 0
1746-OV8 .125A 0
Total = 1.465A Total = .200A
Device +5V +24V
1747-L532 processor .500A .175A
SLC Servo Module .300A 0
1746-IB8 .040A 0
1746-OV8 .125A 0
Total = .965A Total = .175A
