(Note) : Current consumption of A31TU-D3K13(0.26A) is included.
(c) Power consumption of overall modules
I = 0.64 + 1.56 + 0.05 + 0.07 + 0.15 + 0.11 + 0.06
5V
2 + 0.114 = 3.774[A]
Select of the power supply module(Q61P-A1(100VAC)6A) according to this
internal current consumption 3.774[A].
(Note) : Configure the system in such a way that the total current
consumption at 5VDC of all the modules is less than the allowable
value.
