multiple time delay circuit

Need help please.....

I have the following inputs and need to create time delays before the associated 24 vdc relays are energized and then deenergized:

Input #1 = 24 vac constant supply Input #2 = 24 vac when thermostat calls for hot water pump Input #3 = 24 vac when thermostat calls for the indoor fan

Output #1 = 24 vdc immedately when input #2 is applied (output #1 goes off immedately upon loss of input #2)

Output #2 = 24 vdc 30 seconds after input #2 is applied (output #2 needs to remain on for 30 seconds after input #2 is removed

Output #3 = 24 vdc 60 seconds after input #3 is applied (output #3 needs to remain on for 45 seconds after input #3 is removed).

Prefer to have all circuits designed to mount on a common circuit board

Bugger, two hundred and fifty six years and eighty three days of watching this newsgroup and someone comes up with a proper specification.

Then a pseudo Spaniard nicks the contract.

I feel all humble now.

Thanks (erm, obrigado), but you're too much of a nice person.

Anyway, I've got a cauliflower in the fridge that needs some curried cheese sauce adding to it before it goes rotten.

Eeeeeeeeeeh, I do like a nice chuff.

dont worry, the snail season has ended, not exactly northern european fodder, but the locals love it, Caulifower on legs is second best.

But bring some Marmite, I use it as flux on these new ROHS crap components, can't be beat

You can buy delay off relays off the shelf.
