Just a couple other things to add to Ben's comments... you can individually configure, say, one thermocouple point as type-K and the next as type-J, on the same module. Also adjust scaling point-by-point. But you couldn't have one point be an analog input and the next point on the same module as a digital input.
Since you mentioned temperature sensing, also be sure to check out this white paper for more details and considerations when making those hardware/sensor selections.
Do you already have any hardware/software? If not, you might want to download our FREE! [PAC Project Demo (video overview on it [URL="https://www.youtube.com/watch?v=xN45Nx-QftI"]here](http://www.opto22.com/site/downloads/dl_drilldown.aspx?aid=3172)). You can configure I/O points and write flow charts etc. even if you don't have any real hardware yet.
You might also want to try out groov for free here, as a nifty option for your user interface -- we have small touch-screens around the building (both android and Apple) -- and on a number of yachts. For those two applications, the small tablets and iPOD Touch devices are mounted on the walls instead of a clunky/bulky old light switch + thermostat + video camera monitor!
Also don't be shy about contacting our friendly and knowledgeable pre-sales team. They can walk you through that nifty I/O Configuration tool Ben mentioned, and even give you a live demo of the yacht, if you'd like to see that.
Do you ever cruise through Southern California in one of those coaches? We'd love to see!
