Hi

Does anyone knows how could I use the Tunze Osmolator Replacement Pump with RA*? This pump runs on 9 volts DC. I could just buy a DC power supply and plug it on the relay box. Could I also use the Power Control Expansion for a 9 volts DC?

The specs show that it's a 9v DC pump. Get yourself a 9v DC wall wart and 5.5mm x 2.1mm Adapter. Wire that together (observing polarity) and plug that into a port on your relay box.

Looking at the pic in your link it looks like the pump operates anywhere from 7v to 12v. What I can't see on the tag is the actual power consumption. Just make sure what ever power adapter/wall wart you get is rated *above* what the power consumption states on that tag.
