Hi Guys,
Does anyone know if you can get a opto-isolated relay board that accepts 10-32v input (to suit our old proximity sensors) and outputs the required 5v to communicate with pc?

Grayhill, Potter & Brumfield, Opto22 all sell different configuration of I/O boards that any of their plug in opto devices will work with, most of the I/O boards will work with other companies modules.
They come in 4,8,16,32 module positions.
I believe the module you would want to use is Opto22 G40D24.

as Al said - Grayhill, Potter & Brumfield, Opto22 all make these. I think I am currently using all those brands in my project. they all seem to work great. The only thing to complain about would be the opto22 modules don't have a very bright led. (thought something wasn't turning on - figured out I needed to look strait into the led to see that it was on.) That is using 5 volt logic.
