In this video we are going to show you how to wire 4-20mA sensors to the built in 0-10VDC inputs of an Allen Bradley Micro820 PLC using load resistors and scale them in Rockwell Automation's Connected Components Workbench software. Using Ohms law, we can convert the 4-20mA reading across the load resistor of the Micro820 PLC to a voltage reading.
