You'll need to use a transistor to drive the relay.
A circuit like this will work on the green (5v) wire. Use a relay with a 12V coil.

If I passed you on the right, YOU are in the wrong lane!

I've bought 2 of these, which should hopefully work on the +5V green wire ;

That looks like it will work. The issue is the ALP is sending I believe standard TTL I/O. (+5v). Which is just not enough to drive a relay. Using that device will allow you to drive a relay based on the Vcc on the board triggering when the ALP goes high. Let us know how you make out.

From the pdf specification , at 3 volts , it pulls 60ma , i hope it works though as i tested the output
of the source , the max is 45ma .
http://www.iacs.co.uk/download/i/mar...0Datasheet.pdf
Which voltage did you order ?
Morale : please Al team , implement an easy way to trigger a 12 volts relay ....would make our life easier ,
thouh it is already in their plans
Yes, although at 12V supply voltage (the ones I ordered as I will be switching a small 12Vdc load), its quoted as < 45mA 'on'

What are you up to WB? Post in the secure Aussie section if its what I think you are doing...

Thanks Tman - will let you know
This is also quoted in the ebay text ;
Control signal voltage: Data level (3.3v) or TTL (5v) Range is 1-12v DC - takes less than 20mA from logic source.

At 20ma ....i think you got the solution !

I found this cheapy , is it working on the same principle ? they say TTL source for the signal , i guess it needs
another source (5volts) to trigger the relay ....not very familiar with Arduino system.
A bit confusing, as it says 1 channel, but shows 2 x VCC inputs, which I originally assumed would be for a second channel ?
It also says 5V relay, whereas mine, you could specify various input voltages, 12V, 24V etc. I'm not upto speed on electronics, so will let one of the others chime in !
