4-20 mA Current Loop Isolation

4-20 mA Current Loop Isolation

(OP)
We are adding a 4-20 mA output and was wondering if there is a common practice to ground isolation.  Is it standard for the transmitter to isolate ground or the receiver or is it common practice to not isolate the grounds at all?

RE: 4-20 mA Current Loop Isolation

Isolation improves common mode noise rejection.  Stay isolated if possible.
