4 channel relay schematics

[Swartz]

Hi all,
I've got a couple of 4 channel relay boards and are looking for the schematics for them. Since the board can't be found in the store anymore, I ask u guys for help. Does anyone know where I can get it? I'm having some trouble to power it locally.

Hey Eric,
I had stashed that PDF schematic and parts list away on my PC a year ago thinking it would come in handy some day.

Now I actually need a small two relay board and was going to order up the chips from you.
I was just going to cut the design in half and use two relays.

Is that relay board design ok?
Just wondering why it is not avaialble on your site now?

The design is fine. The reason it is not on the site anymore is that we came out with a new enhanced relay board based on the DS2408 chip instead of DS2405 chips.

Ah, ok, great. Thanks

I'll be needing more goodies soon.

I see you use opto isolators on your relay boards now.
