I am currently working on a positioner and have basic knowledge of the functioning. My clarification are how the power for controller is drawn from the 4-20mA current loop.
I understand that the 4-20 mA current loop is being used for both signal as well as power.My clarification is
a. How the power is drawn from the current loop even though the current varies 4mA - 20 mA?
b. How the 4-20 mA current signal is converted into voltage signal?
