(b) 5VDC current consumption of each module
Q02HCPU : 0.64 [A] Q173PX : 0.11 [A]
Q173CPUN-T
(Note)
: 1.56 [A] MR-HDP01 : 0.06 [A]
Q172LX : 0.05 [A] QX40 : 0.05 [A]
Q172EX : 0.07 [A] QY10 : 0.43 [A]
MR-HENC : 0.15 [A] Q38B : 0.114 [A]
(Note) : Current consumption of A31TU-D3K13(0.26A) is included.
(c) Power consumption of overall modules
I
5V = 0.64 + 1.56 + 0.05 + 0.07 + 0.15 + 0.11 + 0.06
2 + 0.05 2 + 0.43
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.
