Temporisation with cd 4060 or /and ne 555

[john120]

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!!

Osc. and 45min timer
Timer Circuits With 4060B - Electronics

instead of transistor use

Time delay circuit for 10sec ( look Time Recovery Delay Circuits)

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.

Help plz!!!!!!!!!

is this what you want:

1. press "button"

2. delay 45 minutes

3. relay activated.

if yes, you want the timer to delay for 45 minutes. I have to check the data sheet to design 45 minutes delay.

Yes,hrlp me for that temporisation I w

Even if it possible for you you can help me to realize with pic16f876a in ccs c.with this I want 8 different period but of the same duration which is 45 minutes.
At the fouth period I Want 30 minutes delay..!!

Thanks!!

Help me plz
