I now have a NGW100 emebedded ARM board driving a relay that switches 240V on or off.
This is wired to a K-type thermocouple that measures temperature up to around 1000 degrees celcius.
The final result is that I can now do controlled temperature profile for SMD soldering. The board monitoring temperature in an electric fry pan, and turns it on or off according to time and temperature to do a nicely controlled profile per the component datasheets!
