Re: relay AC using DC?
1st question .. what voltage is on the green .. since you will need a DCrelay that will operate at that voltage
2nd question what is the power rating or what current will need to go through the relay contacts .. make sure that the relay contact rating is higher than your requirements.
make sure that the relay and all wiring is thoroughly isolated in a plastic box and that teh wiring from the relay coil CANNOT come in contact with the wiring from the relay contacts
usually relays will have a coil rating and a contact rating
the contact rating may be something like 12Vdc 1A or 230Vac 5A, possibly 115Vac 10A,
It's normal for the DC rating to be much lower in amperes than the AC rating
the dc coil will require a diode in reverse polarity to the dc voltage across the coil if you are going to use transistor to turn it on.
a magnetic switch driving the relay will most likely burn out quite quickly if you don't use a transistor to drive the relay. Use the magnetic switch to bias the base of a transistor to ON when it closes the circuit.
