3.
When the resistor (R) is 2.5k, for example, the power capacity (W) of the resistor (R) becomes 0.332W.
2 2
W = (Input voltage) ÷ R = 28.8 ÷ 2500 = 0.332[W]
4.
Because the resistor requires a power capacity that is 3 to 5 times larger than the actual current consumption, the
resistor connected to the terminal should be 2.5k; and 1 to 2W.
5.
OFF voltage when the resistor (R) is connected becomes 4.09V. This satisfies that the OFF voltage of NZ2GN2B1-32D
is 5V or lower.
