I'm a little confused here. If I understand that board correctly, it's for outputs - you provide 12v to operate the relays, and a signal from a microprocessor can switch them - the output stage can support 120-240v, up to 10A.

Since the proxys are inputs to the computer, I don't understand how this board would apply. Did I miss something?

Depending on your BOB and sensors you may not need relays at all. I don't have any with the PMDX125
