Hey,Man who can help me to design a circuit which will activate a relay after 45 minutes during 10 s,I don`t want to use PIC or an other microcontroller type.
I would like to use logic circuits like cd4060,monostable like ne 555 and so on--

Any suggestion is welcome!!
 

Not that,have you tried one of the list.if possible precise for me the one I have to check first.

Let retake the issue,I would like to activate a relay during those 10 seconds but this relay became activated after 45 minutes..

Help plz!!!!!!!!!
 

Can you draw some timing sequence chart for needed circuit.
