    i have a 2 main line of 220 Volt AC Supply.i want to control it and i want to work
    1 line at a time and 2nd is off while 2 is working than 1 line is off.i use a
    Triac in the phase of the both line which are parallel.
    we give a 4 volt +ve only one gate at a time and 2nd is off.

    plz tell me this diagram is true and in this way can we handle it(220 AC)?
    and tell me the Triac number which can u use for this purpose.


    plz urgant reply

    and see the attechment pic

    It's simpler to use two solid state relays for the control. They have all the circuitry inside for controlling the internal TRIACs. Just apply the control voltage to turn them on.

    The selection is dependent on the load current.

    Hello,

    You also must take care of the fact that not both can be switched on at the same time.
    This could lead to a disaster.

    i do not want to use the relay because its switching speed is slow.
    plz tell me the any triac number.and load is maximum 5A.

    yes i know this is most important that the only 1 Triac ON at a time.
    plz tell me the any triac number

    If you look, you will see that the device put forth is a "solid state relay".

    plz give me any solid state relay circuit diagram which can handle the 220 Volt AC

    I am bumping this original thread up for the OP.

    With respect to the SSR circuit diagram, it would be interesting to know if the OP has found the recommended part's data sheet, which describes vital things like how to actually use the device.

    A solid state relay is not too difficult to use. Here is an example for the AQV254H, a high voltage but low current SSR. You will have to adapt it for your chosen SSR, as the one I have specified does not have a high enough rating for your application. But this should get you started.

    Connect pin 1 through a 100 ohm resistor to your control circuit.
    Connect pin 2 to LOGIC ground.
    Do not connect pin 3 as it is not internally connected to anything.
    Connect pin 4 to your AC LIVE through a diode, cathode pointing away from pin 4.
    Connect pin 5 to your load to NEUTRAL.
    Connect pin 6 to your AC LIVE through a diode, cathode pointing towards pin 6.

    As I understand it the diodes used must be rated for the same current as the SSR.

    I have not done much with solid state relays (I prefer TRIACs) so I could be erroneous here. I recommend a second opinion...

    Please be very careful, if you wire this up wrong you could hurt yourself, destroy the relay, start a fire, whatever else.
