I have a 4080 with the standard 3.3 volt extended I/O. I want to connect it to a Opto G4PB16T terminal strip, the Opto modules are 5 vdc logic. Can this be wired to the extended I/O with out letting the smoke out. Or can the 5vdc option be added in the field?

To help anyone else, I got an email, there is away around the 5 volt option see below:
Hello,

I think you are speaking about the 5V option on the extended I/O?

If so, this is not field changeable. We so have a screw terminal module that can be configured for optoisolated inputs and outputs. In this way your 3.3V logic could be used with a 5V supply on the other side to provide the 5V level.

Thanks,
