Off delay Timer

Dear All,

I want to make a OFF DELAY TIMER which switch over after power goes. It works with power stored inside the circuit and switches relay after set time i.e. 0-60 sec.
There will not be any battery inside.

Please suggest.

Regards
Vicky

Without a battery inside, how can you switch a load like relay during power failure? even Super Caps cannot power such loads. I think a battery is mandatory. Cheers
 

To make the relay specification understandable, you should tell what's actually switched by it. With out any power source,
nothing can be switched, even if the relay has a suitable backup power.
 

Try using supercapacitor

A little info about supercapacitor

In fact we may use A latching relay for this.
