Responding to: ???'s previous message
Raghunathan R said:
Incidentally what is wrong with a relay ? Simply power the relay from the mains derived dc supply and use a contact changeover to ground a port pin that is configured as an input.

As I said before, what is the point of a relay?
If you have a mains-derived dc supply to drive the relay, why not use it to drive the port pin direct!
The relay is just an unnecessary complication!
