How to use a solid state relay?

Discussion in 'Electronic Design' started by Gregory R. Ball, Oct 27, 2003.

  1. Hi,

    What I'm trying to do is build a circuit from my computer, where I
    have a controller card I've built that can raise signals, to the wall
    sockets, lights, etc. I want to be able to turn on and off the power
    to the sockets, etc. by raising a signal on the computer. What I want
    to do is run twisted pair wire through the walls and control it via
    that.

    I've done a bit of research and I think I can use a solid state relay
    like jameco part number 164988 for this. Do I just put it in series
    with the A/C current? And run the twisted pair to the input voltage
    leads?

    I'd also like it to default _on_ if the computer is yanked out of the
    wall or something, not necessary but a big plus (it would be nice to
    have electricity if the computer breaks).

    Any feedback would be greatly appreciated. I don't feel like burning
    down my house.

    Thanks,

    Greg

    Assuming it's a standard relay, yes.

    Normally open relays are more common than normally-closed ones.

    Greg,

    Have you considered using X-10 controllers for the lights and such? You
    can buy an interface for your PC to generate the control signals to
    control these devices.

    If you want direct control. Use solid-state relay that have logic level
    inputs and connect them to a spare printer port. Turn individual port
    bits on and off with software in the PC. Mount the relay as close to
    the lamp, socket whatever, then you only need to run low voltage (5v)
    wiring to them.
