Judgment (Example)
a) 5V DC control current capacity check
b) Input/output point connection upper limit check
Calculation result:
The 5V DC power total current consumption value and total input/output points are in the
specified ranges, therefore the above system configuration is possible.
5V DC current capacity of main unit
(value shown in Sec. 1.5.2): 560 mA
≥
Total current consumption of all connected blocks
(value written in calculation form): 475 mA
OK
