I have been looking for a simple solution to controlling a 120v device using a simple low-voltage signal.  Specifically, I wanted something that plugs into a household wall outlet, and then you plug your device to be controlled into it.  There are a zillion such devices that operate using some sort of radio control, but I was looking for a direct-wire low voltage that I can obtain from the output of the Labjack products.


I have found one item, the PowerSwitch Tail, which retails for around $26.

It is, "A power cord that switches 120vac (up to 15 amps) with a dc control voltage of 3vdc @ 3ma to 12vdc @ 30ma"




Does anyone else know of other products like this?

The item you linked looks good.


Other options would be the RB12 with appropriate modules:




... or use digital I/O to directly control an SSR such as the Jameco 176719:
