    Hi guys,

    I was wondering if someone could help me with a circuit diagram to operate this UV light.

    I have a data acquisition card, and have digital outputs 5V. Using this digital output, I want to control the UV light which runs on 120 VAC using a solid state relay as intermediary.

    I am not so experienced with AC wiring; so I would need help. Esp, stripping the UV lights cable and correctly connecting the 3 wires to respective positions of the solid state relay is what I want to know. Thanks in advance.

    Please find someone local that can help you. Line voltages are dangerous. People here can tell you how to connect the wires, but we can't see how you do it. And, it would be a tragedy if you misinterpreted an instruction, and someone were injured or killed by shock or fire.

    Typically all SSR's have a datasheet that shows a typical wiring diagram. Look there if these guys don't want to let you work with 120V...
    Really you are only exposing/splitting 1 wire of the 120V line and assuming you aren't stupid enough to work with it plugged in I don't see the harm.

    If I recall the instruction sheet that comes with those is pretty straightforward, it's basically just a small fluorescent bulb driven by an electronic ballast. If you don't have all the parts don't even try to substitute.

    As to the SSR I'd just look it up, should be examples but as warned above, AC mains circuits aren't to be taken lightly if you don't have any experience with them.
