I thought I knew what a non-incendive circuit was, but we have a new engineer at that is saying we need barriers on all of our instrument loops. Looking for a good web site or some guidance here as to what non-incedive is.
With the above said, if I have a instrument that is rated for use in a class 1 div2 and my DCS is current limited to 25 ma .. I say no barrier is needed?
