• When Total Current Consumption for All Blocks Does Not Exceed the Rated Current
In this example, the current consumption from each power supply is as follows:
Current consumption from Unit power supply: I I_unit2
Lowest rated current
Current consumption from IO power supply: I_io1 + I_io2
Lowest rated current
*1
*1. This is the lowest rated current of all of the Units that supply IO power and are connected to protective
devices. For example, if terminals with both a 10-A and 4-A capacities are connected, the value is 4 A.
