2-1-5 Calculating Unit Current Consumption
Example 2: In this example, the following Units are mounted to a CJ-series Expansion Rack with a
CJ1W-PA205R Power Supply Unit.
Additional Information
Rack Current Consumption and Width Display
To display the current consumption and width of Units connected in the CPU Rack or Expansion
Rack, select Current Consumption and Width from the Options Menu in the CJ2 CPU Unit I/O
Tabl e W i ndow.
If the capacity of a Power Supply Unit is exceeded, it will be displayed in red.
