@dc42 said in PWM to DC for control:
The PWM-to-voltage converters I have seen have optically isolated inputs, so they don't care whether the input is referenced to ground or not. For example, I am fairly sure that this one has: https://www.amazon.co.uk/1-3KHZ-Voltage-Module-Digital-Converter/dp/B0789738RC/ref=sr_1_5.
Thank you very much for the quick reply. I will try out the converter with the optocoupler.
