that is not good idea use 6009 for this one but your answer is 2 motor with analog out put and 8 motor with digital output and you just need to use amplifier to convert 5 dc volt to 12 dc also depand on your fan current use you have to use some amplifier for 20m am to that current this is all I know but try use some isolate method before it to make your daq in safe mode
