I would like to build a circuit using a 24vdc power supply that would give me an output of 4 20ma or wider range to supply the loop power to manually control a valve while a new controler is installed. 4 20ma signal generator circuit for 24vdc devices i would like to build a circuit using a 24vdc power supply that would give me an output of 4 20ma or wider.

In this tutorial video we will learn how to generate 4 20ma signal in our lab using dc power source and variable resistance. For example if the voltage of a 2 wire transmitter is specified as 15 to 24vdc the lower voltage is the minimum voltage necessary to guarantee proper transmitter operation. In general an expensive isolation amplifier would be required to detect the case of a 4 ma signal falling out of spec e g 3 7 ma without degrading the isolation of the 4 20ma current loop.
