convert 4-20mA to 0-5v by 250 Ohm resistance for KC868-COLB/COL
#1
KC868-COL support use analog sensor that 0-5V output, if you already have 4-20mA sensor. you can use a 250 Ohm resistance connect with signal input port and GND to convert.

To convert a mA analog input signal to voltage you need to attach a inline resistor. The size of your resistor will determine the output range of your voltage. 

Resistor Calculations are as follows:

Using ohms law V = R(I)  (Voltage = Resistance * Current)


If we were to scale a 4-20mA to 1-5V

For the 0 Value: .004 Amps * 250 ohms = 1 Volt

For the Max Value: .20 Amps * 250 ohms = 5 Volts

this is a sample for AI1 and AI3 input use by 4-20mA sensor to convert to voltage signal by 2pcs 250 ohm resistance.
