555 timer circuit to control 12v solenoid air valve (for intermittent bursts of air).

Cheers Clive..!

That's me being dumb again...! If it helps anyone else reading this:

The output is the relay contacts RATED at 24V 3A and not outputting anything. ie the relay is just a switch that changes state. So the control circuit runs off 12V and you can run the air valve off 12v through the relay.

Thanks again Clive!

Hi Wal

the Velleman kit should make it easier

looking at the circuit it runs of a 12V supply - ideal for your solenoid valve (don't forget to add the diode across the coil)
