- In industrial settings, there are many commonly used circuits when connecting sensors to PLCs. 4 to 20 milligrams current loop circuit is common for analog devices. In this LinkedIn Learning course, I'll give you an overview of 4 to 20 milligrams current loop circuit, covering the definition, the loop components, as well as an example of wiring an analog sensor to a PLC input module. I'm Zara Khalil. I am an engineering instructor and I enjoy teaching courses covering topics on industrial automation and PLC ladder logic programming. Let's get started.
