Hello!
It’s very very hard to find I/O-Modules/GPIO’s which works for/with industrial 12-24V, (rather than only 3.3-5V) regardless if you search for use for Arduino/BeagleBone/Raspberry/MinnowBoard/Edison…
There exists a ready to use IC, called “iC-JX from iC-Haus”:
http://www.ichaus.de/product/iC-JX
but it’s a very little SMD hard to connect with the I/O pins or better with SPI of Arduino/BeagleBone/RaspBerry/Edison/…
I would be very glad to buy a Breakout Board for this iC-JX, or better an Arduino Shield, BeagleBone Cape, Edison Block, …
Thanks.
