Good question, it depends on the relay that is in the box. You have to be able to turn it on with the 5VDC signal from the interface card. I'm going to guess that it might be fine, but you will have to look at the data that should be on the relay itself. It is also possible that the DB-25 connector directly connects to the drives and relay, so it's just a matter of building an adapter cable between the board and the box. This is something you are going to have to figure out. Without the box, or a schematic in front of me, I couldn't even make a good guess.
