I/O triggering

I am setting up around 20-30 contact closures to control sunlite. i know this is possible to do with combinations of the pins on the back of the controller box, the problem is making all of these different combinations. The best I have thought of is using relays to make different combinations of 4 pins. Idealy i would like to have a box that i can directly short out two pins to make a number 1-255. The box would have a pin for every switch i want.
I'm not sure if that makes sense to anyone but...
Is there a unit that i can easily do this with or should i use relays?
