How to Program a PID Loop
This tutorial shows you how to read an analog input current (4-20mA), display the raw reading, and convert the signal to more meaningful values on the User Interface.
Software Required
Hardware Required
- HMC4070A-M – Other HMC2000/HMC4000 models can also be used
- 24 VDC Power Supply (4010-0011)
