Isolated 4-20mA current loop transmitter

Interfacing Isolated 4-20mA Current Loop Transmitter Arduino

Interfacing Isolated 4-20mA Current Loop Transmitter Arduino In our last post we interfaced 4-20mA current loop receiver with the arduino, in this article we will learn how you can interface isolated 4-20mA current loop transmitter board with arduino. 4-20mA transmitter devices are used to provide 4-20mA signal which can be used to control pumps, valves, switches and transducers. For example lets say you want to want to control a sprinkler which works on 4-20mA current loop signal, in that case you will need a 4-20mA current loop transmitter board. To control such a sprinkler you will change the current output
