Programable multi-output/input relay
Make it breakdance to the beat if you really want to...
Since the output is triac - I would suggest having it operate small coiled relays for current and short isolation - just in case....
Attached is a simple diagram an input to start, a flasher timer and a cam sw - reseting to red - cycles R,O,G in equal predetermined seconds....
Your looking at like ~$250+ Depending on where you locate it, and what type of control voltage, how many outputs if you want a display or not etc...
Software is free on line - doesn't take long to figure out - what more is you can change what you want it to do and how it operates or starts... i.e. put some contacts on the beer tap and a counter for when you need to be shut off....
Or sound a 10" fire bell and flash the lights for when you should have been shut off some time ago....
