I am not sure in what forum to best ask this question.
I have 3 gas monitoring devices requiring 3-wire wiring scheme. As this is my first time doing this I am not sure what is the difference between a 2-wire scheme and 3-wire scheme. Does anyone know of any good online resources that shows a typical wiring diagram of this?
Thanks all.
