    It's just that I'm gonna be hooking up quite a number of things to it and getting a relay card with only 4 relays just isn't going to be enough.

    Are you thinking of driving the windows directly off the I/O card?

    Even if your window is negatively controlled, be very careful cause the card can only sink 2A. I dont know how your window is wired up but if you are gonna sink more than 2A from that card you will blow it.

    Ill stick with a relay to be safe, unless the window switch is only controlling a relay coil and not the windows motor directly.


    You can still buy the 16 I/O card and connect 16 relays into it.

    Well, I did and I thought I had it all under control, but then I saw their little tutorial on how to use a motor with a digital output and it got me confused.
