hi is there any solution to use SIL3 analog output barriers?

 

It appears you have not seen the links ‘similar threads’ below these postings relating to SIL3 designs.

The short answer is what specification you have of each barrier type making it suitable for inclusion into SIL3 designs. It’s unclear from your question what you are looking for, since a SIL3 calculation is based on a complete system not individual components such as barriers.
