We have a VF3 with the additional m-code relay board on it. Would like to wire in a solenoid valve for air so I can control the air going to our mister. Does anyone know what the max. voltage and amperage is for this board. Do I also need a diode in the circiut to prevent from backfeeding voltage into the board. Have looked at other posters posts (helicopter johns) on how to do this but being this is a older machine wanted to check first.
Have contacted Haas but they only send me the paperwork on how to install the board and what m-codes to use.
Thanks!
