Dear all :
Can anybody point me to literature that will explain the operational principles of a Loop-Powered panel meter ?
I have also read about "4-20mA" . Is this some kind of standard in the automation or communications community ?
Please excuse the newbieness. I guess everyone has to start at some point in time. Thanks for your patience.
