24v ports

I really need my aquarium controller to have 24V or 12V DC ports that can be turned on for a few seconds o a few minutes at a time at specific points in the day. It's for a frozen food dispenser. @Lasse, I guess you may know this one! Thanks a bunch to anyone who'll chime in!

As the title says I think neptune should make a new module with 24v ports. I can think of a lot of uses for 24v ports, lighting, pumps, solenoids, etc. Lots of low voltage options to think of but so few ports available. I have an idea for controll of an ro system, and it will require 5 24v...
