Hello @beergeek
You are right with problem when using analog output in configuration 0-20mA. When we designed nodes, we only implemented voltage output.
To fast repair you can add function node to output, that recalculate output value from 0-10 to 0-20. So your input value will be 0 to 10, but output value will be 0-20. We will try to repair output node with support for current output it in next week.
Function code to fast implementation:
0_1562793741763_b5537379-d362-4d19-b00b-00d50f3b5464-image.png
Try to import funtion and connect it as in picture.

Thank you for your notice.
