(g) Average power consumption of the input section of the internal input circuit
and input module
W
IN = 0.005 24 4 1 + 0.004 24 16 1 = 2.016 [W]
(h) Power consumption of the external power supply section of the intelligent
function module.
W
S = 0.12 24 = 2.88 [W]
(i) Power consumption of overall system
W = 18.975 + 4.744 + 40.32 + 0.54 + 2.016 + 2.88 = 69.475 [W]
