You don't mention a current requirement. Crydom makes solid-state relays
that interface TTL-level signals to AC power, and boards to hold
collections of them. National Instruments makes digital I/O daughter
boards, and provides them with software drivers. They probably sell them
connected by a cable to a (Crydom?) external board. You may be able to
get all the digital I/O you need from a modern printer port. Look at
