Hi there.

I have got this Solid State Relay , and i wanna make a circuit so that i can use this relay to take an input of 5V and give me an output of 110V (enough to lightup a bulb of almost 60WATT).

What else do i need to make this circuit?

BTW i have heard that breadboards are not a good choice to deal with high voltage, what should be the choice then?

BTW here is the pic of the SSR i have.

I'm hesitant about your understanding of electricity & safety, please be careful.
First, I don't see how a breadboard can be of any use in this circuit.
You need 5V, 110V, 5 pieces of wire, 1 socket, 1 bulb.
Wire the bulb in series with terminal 1 or 2, and then connect the other terminal and the other end of the bulb to 110V.
Apply 110V.
When you then apply 5V to terminals 3 & 4 the bulb will light.

But you already know that from replies on the other board you also posted in:

Thanks for the replies.

I have a very little knowledge about these high voltage AC circuits so i am trying to gather as much info as possible before jumping into this kinda stuff, thats why i am posting in other forums too.

Ok then forget about the breadboard, i ll not use it.

You said i need to wire the bulb with Terminal 1 or 2 in Serial, can you please elaborate this? Did you mean to connect the the terminal 1 or 2 of SSR to the -ve(GND) of the Bulb?

Here is my understanding of this circuit

No problem posting in several forums, but I saved myself a whole lot of typing when I happened to discover that.
The circuit you posted here is just the way it's supposed to be.
The SF20DPS-H1-4 has a built-in resistor in series with it's IR-diode and is specified to work with an input between 4 and 7 Volts.
I don't know though how much current it draws, and how much current the Arduino ouput is capable of delivering.
If the output from the Arduino is too weak then the voltage will be too low and it might not work properly. In that case you only have to add a transistor on the breadboard.
There are several configurations possible in that instance, but if you use the emitter-follower configuration you don't even need an extra resistor.
A diode is only required across the coil of an ordinary relay.

Arduino pin delivers 40mA of current, i think it should be ok to use with SSR, or should i somehow calculate the amount of current required for SSR to operate?

Ok, you're good to go then, 40mA should be plenty, the SSR surely draws less than 20mA, more likely around 10.
But you'd have to measure the actual current if you'd want to know for sure. I found no data on the net about the resistance or current.

BTW whats your say on this Relay

http://panasonic-denko.co.jp/ac/e/co...ance/index.jsp

I am interested in AQG12105

You can see the Picture on the Basic Information Tab

It'll work just as well, using loads from 2 to 110W, and has an input current of 10 to 17mA.
It'll have to be soldered on a PCB, or maybe it can be used with "screw terminals in-a-row".
