In that case, refer back to my post (#4). We used a very similar system using spike relays in 2014 in java; there's no reason it would not work with DIOs using the relay module I listed. (Both the team and I have used these modules with Arduinos.) Using this or a similar 12V relay module with the common ground jumper removed, the DIOs only need to drive a tiny LED on an optoisolator (already ballasted with a resistor on the module), and you can use unregulated 12V to drive the relays and the LEDs. Unless you have an unusually long strip of LEDs, you can power all three colors and the relays off a single PDP breaker.
