How does a 4-wire current loop work?
How to connect a 4-wire transmitter to a PLC?

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

💬 Video Summary:

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

By bringing the power supply voltage to this 4-wire angular transmitter, we turn it on and make it operational. From here, the connection is pretty straightforward.

The positive polarity of the transmitter milliamp signal connects to the positive polarity of the PLC analog input. Also, the negative side of the transmitter goes to the negative side of the PLC analog input.

Through these separate cable cores, the transmitter brings the 4-20 milliamp signal right over to the PLC analog input with a return path.
