looking for small plc

[Guest Guest_Randy]

I am looking for a small cheap plc to controll the heating, cooling, and lighting of a saltwater reef aquarium. i have used direct logic and allen bradelly however they are too expensive and I would be wasting alot of memory with either of them. In the past I have seen cheap plc designs with hand controllers but now that I want one I cant seem to find any. I would like to keep the price under $100 for the plc and a reasonable amount for the I/O module and analog module. if anyone knows of such a beast please reply.

A common problem with looking for a controller on Ebay is that the software is usually not included. So, you are buying the controller and have no way of programming it. Some of the programming software is very expensive.

I use SLC 100/150 on LOW budget jobs. If you time the bid right, you can get one for $25. They're not as much a pleasure to program as modern PLCs, but they'll do all the basic stuff and in my experience are very rugged and reliable. Software and programming cables are available on ebay also.. You should be able to get software, cable, and controller for under $100.
