I/O boards

Does anyone know of series of input/output boards that have some sort of method to communicate to open hab? Zwave or ethernet perhaps? A standard contact closure/open to activate an input and just form C relays with NO, C, NC. Ideally at least 8 channels per board?

I am looking to control random devices through relays but also hope to have random devices hardwired to inputs. Together I can have input, output functions written to automate certain activities.

Thank to all for your help.

That should at least suggest some search terms

I was exploring these:

The first two are respectively 16 inputs (ioLogik E1210) and 16 outputs (ioLogik E1211). Sites like industrialnetworking.com have pricing and PDFs that do not require login.
