4-20mA Signalling

Help & Support Robot Parts
1

I am looking for a multi channel 4-20mA testing board to help with product developement and testing.
Ideally this would be for the raspberry pi and would be programmable in python.

Does anyone know of a board which has say four outputs and four inputs that would work with the pi.
I could lay one out myself in kicad but this would take me about 3 days work.
I’d rather buy one. Found some OUTPUT ones that are single channel on
ebay, but no multi channel.

Hey @robin48gx

I don’t know of any board that includes inputs & outputs together. Therefore, you may very well be stuck with making one yourself.
I glanced at this thread and it seems to have plenty of info and possible options.

I hope this helps.

Sincerely,
