How to wire analog 4-20mA sensors to the 0-10VDC inputs of an Allen Bradley Micro820 PLC and scale

In this lesson 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.

While the Micro820 only has 0-10VDC inputs, we can use a 250 ohm resistor and Ohms law to connected 4-20mA sensors to them.
