Use a diode 1N4007 or similar in paralell with relay coil (in reversed
position) to protect transistor from back emf spike when coil is turned off.

Hello Everyone,

I really have not done much with AC before, but now I have a need. I
want to switch AC on and off using the stamp. What I'm going to try
is switch it on with a relay. It is a relay that I picked up from
Radio Shack that turns on at 5V. Its contacts are rated at 120VAC
and 24VDC.

I have a transistor switching on the power supply for the relay. Are
there any precautions I should take when using AC like this? Will I
blow something up?

Thanks,
FS

I am using a SSR (solid state relay) on a project and works fine:
- The Led of the SSR is connected to a Stamp pin through a resistor, that's
all.
- The load is then driven by the Triac of the SSR.
