Ground Loops/Signal Isolation


Thread Starter

Can anyone recommend a good reference or source of information about standard wiring practices to avoid ground loops pertaining to analog signal measurements (i.e., 2-wire/4-wire)? I've looked at the ISA standard S50.1, but there is very little information there.

You might want to look at Allen-Bradley website for Publication 1770-4.1 titled "Industrial Automation Wiring and Grounding Guidelines"
