Definition - What does Current Loop mean?
Techopedia explains Current Loop
The devices connected to a current loop may be active and have their own power source, or they may be passive and rely on power from the loop.
There are different types of current loops, including long telecom line loops, discrete control functioning loops and other kinds of process controllers.
This type of electrical engineering has been used extensively in telephony and in two-way radio systems.
A current loop can often be easily monitored using a multimeter.
