WHY WE NOT USE 2-20mA,1-20mA,3-20mA or 10-50mA SIGNAL?
INSTEAD OF 4-20mA.

Answer Posted / mike betts

I am not sure why the range of 16mA i.e 20 - 4, but the 4mA
starting is so that you have a posative value of current for
all values that the loop current represents. This way, if
you have no current at all, the loop is open circuit for
some reason.
