Yes Ron,
my question was related to the first post, namely the use of the optocoupler as 230 VAC main sensing. I thought maybe it was understood.
As Ron has noted there is specialized optos's depending on the application, the Fairchild AN-3006 shows detecting the mains AC with opto coupler.
I have used this method in the past.
Max,

There was also a comment about producing a product. One important consideration in product design is part availability. A design that can use products from a number of vendors is much more likely to always have a source of parts available that a design locked in to one specific component that is not multiple sourced. In addition, multiply sourced components are often less expensive.
