Hi Guys,
I'm wondering if there are applications where 0-20mA ( 0r 4-20) might work better, or be more appropriate than 0-10v?
I have noticed that with some of my analog inputs that I seem to get more noise on the 0-10v than I do on the 0-20mA circuits, especially around the low end of the range. Even when my mA signal wire is unshielded, and the 0-10v signal is shielded. I've tried it both ways, with no significant improvement.
I guess I'm looking for a pros and cons list comparing 0-10v to 0-20mA?
