I cant find any electrical specifications on the S0meter S0PCM-5.
I need to connect an inductive sensor for my water meter, and a IR-led for my electrical meter.

Is the S0-inputs pulled up internally by the S0PCM? To which voltage? What is the maximum permissible voltage at the inputs?

Suggested to ask the supplier of S0PCM more direct at http://www.smartmeterdashboard.nl/contact

Received it. It has 5V with some 50KOhm reistance (or so..).
Best method is to use an optocoupler.
