CJ1W-PA/PD
Example: Calculating Total Current and Power Consumption
Example: When the Following Units are Mounted to a CJ-series CPU Rack Using a CJ1W-PA202 Power Supply Unit
Note: For details on Unit current consumption, refer to Ordering Information.
Using the CX-Programer to Display Current Consumption and Width
CPU Rack and Expansion Rack current consumption and width can be displayed by selecting Current Consumption and Width from the Options
Menu in the CS/CJ/CP Table Window. (The width can be displayed for the CJ/CP Series only.) If the capacity of the Power Supply Unit is exceeded,
it will be displayed in red characters. For details, refer to the CX-Programmer Operation Manual (Cat. No. W446).

Result 1.59 A (≤ 2.8 A) 0.096 A (≤ 0.4 A)
Power consumption
Total 1.59 × 5 V = 7.95 W 0.096 A × 24 V = 2.304 W
Result 7.95 + 2.304 = 10.254 W (≤ 14 W)
