In this video, we break down how 4–20mA loops actually work in industrial controls systems.

We’ll cover:

* what a transmitter does
* what the PLC actually reads
* why industry uses 4mA instead of 0mA
* and how 4–20mA signals are used in the field.

This video is made for:

* electricians
* controls beginners
* instrumentation techs
* PLC learners
* and anyone trying to better understand industrial automation.
