Example power requirement calculations
For an sbRIO-9602 with three installed board-only C Series modules,
20 mA total current through 3.3 V DIO pins, and 1 A of current through
5 V output, calculate the total power requirement as follows:
Pint = 6.0W
PCSer = 3.30 W
PDIO = 0.08 W
P5V = 5.55W
Adding 20% for transient conditions, 14.93 W × 1.2 = 17.92 W
Total power requirement = 17.92 W
For an sbRIO-9601 with one installed board-only C Series module,
330 mA total current through 3.3 V DIO pins, and no 5 V output used,
calculate the total power requirement as follows:
Pint = 6.0W
PCSer = 1.10 W
PDIO = 1.28 W
P5V = 0.00W
Adding 20% for transient conditions, 8.38 W × 1.2 = 10.06 W
Total power requirement = 10.06 W
