Ive used NDIO modules before, but never with an active input. I want to tie in a CO sensor that uses 0-10V, but can an NDIO board supply DC power to a sensor?
Thats what I thought, looks like I need another controller. Digo, where did you get that info about the 24v transformer?
IO-34-H Input/Output module Installation Instructions.
IO-16-H doesn't mention it.
Thanks Digo, that power wiring is referring to NDIO power. I want to use a power supply that is powering something else for the CO sensor. I dont think that should be a problem.
Why not use a CO2 sensor that uses AC ? Most do either AC or DC as the power supply with a 0-10vdc signal out.
What sensor are you using?
The sensor I want is both ac and dc from kele. I just figured it would be easier to power it right from the controller. Im just going to steal 24v from one of the rtus in the building.
