Tim Fischer Posted July 14, 2012 Share Posted July 14, 2012 Do I need to join 1-3 pos together to yellow?tjNo, they are joined on the circuit board of the CMB16D already Link to comment Share on other sites More sharing options...
james campbell Posted July 14, 2012 Share Posted July 14, 2012 No, they are joined on the circuit board of the CMB16D alreadythats right,the positives are always hot,and the negs are what switch the power on and off Link to comment Share on other sites More sharing options...
tjflory Posted July 14, 2012 Share Posted July 14, 2012 (edited) ...Ooooohh. Now it all makes sense.Somehow I thought I read all channels were completely seperate circuits.I plan on using it with 12 volts on 1 side for RGB LED spotlights and 24 volts on the other side for my fountain valves... sound do-able?Thank you all!tj Edited July 14, 2012 by tjflory Link to comment Share on other sites More sharing options...

Steven Posted July 20, 2012 Share Posted July 20, 2012 I plan on using it with 12 volts on 1 side for RGB LED spotlights and 24 volts on the other side for my fountain valves... sound do-able?That's doable, as long as your 24V power supply is DC, and the valves work with DC. (I seem to remember that standard 24V valves are typically used with 24VAC.) Keep in mind that the two power supplies will have their negative outputs connected together. This means that you don't have to reserve 8 channels for LEDs and 8 channels for valves. You can hook your RGB LED red, green, and blue leads to the negative (-) side of any 3 channels, and the positive (yellow) lead to +12V, which will be available on the side where you hooked up the 12V supply. Each valve will be connected to the negative (-) side of any channel, and +24V.This means you could potentially use 3 RGB spotlights and 7 valves, or 2 RGB spotlights and 10 valves, or any other combination that uses 16 channels or less.

Timon Posted July 21, 2012 Share Posted July 21, 2012 I plan on using it with 12 volts on 1 side for RGB LED spotlights and 24 volts on the other side for my fountain valves... sound do-able?Make sure you put a 1N4004 diode accross each valve to counteract the back EMF so you don't blow out the MOSFETS. Make sure the cathode is connected to the common +V and that the diode is at the coil. Link to comment Share on other sites More sharing options...
spomalley Posted July 21, 2012 Share Posted July 21, 2012 Orville mounted external LEDs on his controllers and there is a topic showing how he did it I can't find it though. Link to comment Share on other sites More sharing options...
rgardner518 Posted October 2, 2012 Author Share Posted October 2, 2012 Any more info on how to add a remote LED to the DC board other then with fiber optics? Link to comment Share on other sites More sharing options...
