🎥 By watching this video, you’ll get the answer to these questions:
- How does a 3-wire current loop work?
- How to connect a 3-wire transmitter to a PLC?

======================================================

💬 Video Summary:

- In a 3-wire current loop, we have a power supply, a 4-20mA level transmitter, and a receiving device such as a PLC analog input module.

- From the positive side of the power supply, we bring 24 volts to power up the transmitter.

- Then the transmitter generates its desired signal current, which is the 4-20 milliamp signal going to the analog input of the PLC.

- And as the common side of the transmitter and the common side of the PLC analog input are the same connection, the return path of the 4-20 milliamp signal is as shown in the video.
