Figure 2.5-6: Connecting to a 4 ~ 20 mA Source

AI CHn

AGND

(Shunt Resistor)

Example:

A 20 mA source current through a 125 Ω resistor (e.g. 125 Ω, 0.1% DIP Resistors) between

+ and – terminals and the board will read a 2.5 V

voltage. You can use the

I = V/R

(Ohm’s law) to

calculate what value the source current should have.

Current (I) = Voltage (V) / Resistance (R)

= 2.5 V / 125 Ω

= 0.02 A

= 20 m
