something like a turbo timer but with out the price?

Someone posted a link to those relays once. They were pretty damn expensive!

yeah ive had a search around here and only found them..
there is gota be an easy way to build one..
i was gona search the net some more but i figured someone here might know

there is a cheap turbo timber on ebay au for au$30 which would do what i want..

If you're into DIY projects and know how to use a soldering iron, use the 555 IC chip.
Run a Google search on Time Delay 555 and see the examples. To make it do the work for you, use a proper relay on the other end (insead of LEDs as they appear in many examples). You will be able to set the time correctly (up to 10 mins) by getting the correct amount of resistance and capacity (you'll see those in the various examples).
Good luck.

I bought a DEI 528T pulse timer relay on ebay for $25. Retail is $49. There's some on ebay right now for less than $20 shipped, can't beat that IMO.

They work great too. But the details on those auctions are incorrect, it's max 15 amps. Any more and you need to use it with a seperate relay.

scroll down to the ELK-960

I use that right now, after ~60 seconds (which you can change from a few seconds up to 60 minutes, I just happen to use 60 seconds), it cuts off the relay so when I hit the switch to shut off my opus, if a software lockup occurs, I can walk away and not worry about my battery being drained (which happened to me before I bought this timer).

The timer is VERY programmable, you can set it to start counting when you switch the input high, switch it low, cut off the input, all that jazz. I think it can repeat, a bunch of other stuff.

I forget where I bought it, was too long ago. The link I gave above is around $21 (before s/h), and that's right around what I paid. May be able to find it for cheaper, I dunno.

Nice product too. Relay can't handle a LOT of current though. I intentionally just bought a 30 AMP relay as well for a couple of bucks. That way this fancy relay just controls the 30 AMP relay. Has worked beautifully for me thus far.

Good luck

there's the product page direct from the manufacturer

you can look into the pac tr-7.. it has a lot of features & can do what you are looking for too

This is what I got from a friend of mine when ask him for a timer relay for a little project that I have in mind


It work for 0-15 min.

Thanatos.
