Hi Ziko,

So, I set the jumper to EXT, then connect a 24V supply across +V & GND. Then I can get a 24V supply to each of my sensors from the +V output on each channel, correct?

Thanks,

Richard

I see from the Enviromon manual that the EL037 can be used to provide a 12/24V supply to sensors, but it does not explain how to do this. I can see that each channel has a +V connector for the supply output, but where does the supply some from? Does it need to be connected to the +V & GND connector ...
