X10 transmitter with binary input?

[daryl]

I would like to use X10 to communicate the on/off state of a special purpose sensor device I'm bringing to market.  The device can generate a 3v logic signal.  Is there an X10 controller that will accept such a binary signal and act like a simple on/off switch to turn on or off a simple lamp module?  Failing that, is there a reference that can show me a design for a simple on/off contoller such as is used inside an X10 wall switch transmitter?

Thanks!  That certainly looks like a good candidate, except for the 6-18v input range.  I may have to arrange for a reed relay to drive it.  Pushing my luck here: is there a simpler device?  I'm hoping for a cheaper solution that will simply turn a light on and off; I don't need three modes with full house lighting control.

The Power Flash is about the "cleanest" X10 solution if it works a 3V, but you need to experiment. I have Power Flash triggering at 5V input. If you went the reed relay route, you could hack just about any X10 controller and (i.e. the "mini or maxi controller") accomplish the task.
There are also non X10,  RF controllers that turn on a special light switch or module. They are usually marketed as a cheap way to add three way control.

Many third-party devices use the X-10 TW523/PSC05 as a powerline interface for X10 signalling.  If your sensor product involves a microcontroller, this may be the best way to go.
