= (Current consumption from I/O power supply)
= 10 mA
= (Current consumption from I/O power supply) + (Input current × Num-
ber of inputs used)
+ (Total current consumption of connected input devices)
= 0 mA + (6 mA x 4 points) + (50 mA x 4 points)
= 224 mA
= (Current consumption from I/O power supply) + (Total load current of
connected loads)
+ (Total current consumption of connected output devices)
= 10 mA + (125 mA x 4 points) + (50 mA x 4 points)
= 710 mA
= (Current consumed by NX-PF0730) + (Current consumed by NX-
ID3317)
+ (Current consumed by NX-OD3121)
= 10 mA + 224 mA + 710 mA
= 944 mA
