WebDec 30, 2024 · R = 10/0.02 = 500 ohms. This is going to be our resistor's value. let's calculate what will be the converted output for 8 mA. V = … WebJul 8, 2016 · A 1/4 W resistor will last forever. ... or the input impedance for the 4-20 mA input is 200 ohms. Almost certainly 250 Ω (not 200) because you would be jumpering in the resistor across the 0 - 5 V input so that 20 mA gives 5 V. R = V I = 5 20 m = 250 Ω. The 4 - 20 mA will be read as 1 - 5 V by the analog input. Share.
