Built a building monitor system around two of these modules. 16 relay-driven circuits put eveything from heaters to the main compressor under computer control. Inputs from security alarm mean everything shuts down when building is locked - no more compressors running all night. Never a problem. Great device. Looking for reasons to use more.

I love this! Yay Velleman! :) :)
Great kit to build, easy enough, and great to use. There is really good documentation availablefrom Vellemans website and getting it up and running might take a couple ofhours, but when it works, there are soo many opportunities for creating real cool things...
Definative buy. :) :)
