What is Scaling in PLC? - How to Scale the 4 to 20 mA Current Signal?

In this video, you will learn what is scaling in PLC and how to scale the 4 to 20 mA current signal. The changes in the process variable affect the electrical analog signal (4-20mA) and that happens inside the transducer. Then the changes of the analog signal (4-20mA) are to be translated into digital values using the ADC "Analog to digital converter (0-27648). And that happens inside the Analog module. Then this value; the digital value is transferred to the CPU. ## Free PLC and SCADA Training Courses ## 1. Free Siemens PLC Training Course https://instrumentationtools.com/siemens-plc-training/ 2.
