The total current consumption of the components in a PC must be less than the
capacity of the Power Supply Unit being used. For example, a CQM1-PA203
Power Supply Unit (capacity: 3.6 A) can be used with a CQM1-CPU21-E CPU
Unit, two 16-point DC Input Units, and three 16-point Contact Output Units, as
shown below:
Current Consumption = 0.82 + (0.085 × 2) + (0.85 × 3) = 3.54 A ≤ 3.6 A
