  • Are lights or appliances in one area of your house having trouble receiving signals from Insteon transmitters in another area of the house? This problem is easily correctable with the Insteon Hardwired SignaLinc Phase Coupler (also called a signal bridge).

    Because most homes have 2-phase 220V power that splits into two separate 110V legs, sometimes automation commands have a hard time making the transition from one leg to the other. But connect the Hardwired Insteon SignaLinc Phase Coupler to your home's breaker box, and it will bridge Insteon signals between the two power lines in your home easily, allowing virtually all of your automation receivers to respond to Insteon signals.

    How do I Know I Need a SignaLinc?
    Here is an easy test you can perform to see if your home would benefit from a SignaLinc. Find the Insteon -compatible transmitter and receiver that never seem to work together and try sending a signal between the two right now (still not working, right?). Then, turn on a 220-volt appliance, like your electric oven, clothes dryer, or central air conditioning. It has to be an all-electric appliance; turning on a gas dryer won't work. Now, go back to the transmitter and re-send the signal to that problematic module. If it now works, then you've proven that a SignaLinc will help the Insteon signals in your home. In this test, the 220-volt appliance acted like a phase coupler.

    New Design, Only Two Wires to Connect
    Unlike many other hardwired solutions that require a neutral connection, the Hardwired Insteon SignaLinc Phase Coupler offers easy two-wire connection (plus the ground wire). That makes it ideal for older homes that may have a limited number of openings on the neutral bus bar. Additionally, the two-wire design allowed our engineers to improve the coupling between phases over traditional signal bridges.

    Can I Install it Myself?
    In most cases, yes. If you've ever replaced a broken circuit breaker, then you have the experience to install a phase coupler. You will need two dedicated 15-amp circuit breakers (available at a home improvement center). If you have more than one electrical panel, the SignaLinc should be installed at the panel closest to the point where electricity enters the building. If you choose to have an electrician install it, it should be no more than an hour's job to mount and wire it.

    Note: The Hardwired Insteon SignaLinc Phase Coupler is a passive coupler and does not amplify the signal. This means the signal coupled onto the receiving phase will be no stronger than the original signal on the transmitting phase. How well the SignaLinc works in your home is dependent on many factors, including signal strength for the transmission phase.

    ( ETL Listed Mark)The Hardwired Insteon SignaLinc Phase Coupler has been tested, investigated and found to comply with the requirements of the Standard(s) for Information Technology Equipment (UL-1950) and are identified with the ETL Listed Mark. The product with this mark on it has been certified by Intertek Testing Services (ITS). This certification mark indicates that the product has been tested to and has met the minimum requirements of a widely recognized (consensus) U.S. product safety standard, that the manufacturing site has been audited, and that the applicant has agreed to a program of periodic factory follow-up inspections to verify continued conformance.

    Smarthome: Please Start Selling the Compatible Wallplate for These Review by Chuck
    Smarthome: Please Start Selling the Compatible Wallplate for These

    The wallplates for these are impossible to find. A very special and unusual screw spacing. Smarthome needs to carry them.

    Works good but it is better to have more than one insteon dual band device installed on the opposed phase. This way the signal is repeated. this device is a passive couples, works, but the signal power is not increased between phases but divided.

    I installed the SignalLinc and unfortunately I am still having intermittent operation of my X10 controlled house. Did I buy the wrong device?

    no power indicator light, no signal light, with wire nuts connecting the wires, it's now too big to fit in a single size box.

    A little bit more complicated but no hill for a climber. Follow the directions and it does it's job.

    I had some switches on the other phase that didn't work with X10. This unit fixed the problem. I recently got the switches working on Insteon protocol and it works great for that too. The only down-side to this device is the holes for screwing the blank cover plate on are the same ones that are used to hold the unit into the electrical J-Box.

    Review of 2406h

    If it for Insteon phase coupling why does the specs say INSTEON Messages Repeated: No ? Is this any better than a CP000-11 X-10 coupler?

    Smarthome response:It will pass the powerline signal (X10 or INSTEON) to the other phase, thereby coupling the phases. What it means by "INSTEON Messages Repeated" is that the unit is passive and does not "echo" the signal it hears. The functional difference between the two models is negligible.

    Works great. Should have spent the money on this product instead of trying to save money on a $1.00 piece of junk on Ebay.

    Installed on main breaker panel without difficulty. Systems is running well, but hard to tell the exact contribution of the coupler.
