Hi guys, I have found in the old forum a guy that had the same problem as mine: control a device that is 0-10V controlled with the 0-5V from the Arduino. One of the users answered this solution, but was not sure about the resistors values : Assuming my device needs 200mA and using a 2n2222 tran…

Variable 0-10V from 0-5V

It's a Electronic Proportional Control Unit (E908A001).
And what do you mean by "real" 0-10V? That it will more likely output 1-9V?
