Essential Info

With the X10 Signal Coupler Repeater, you can solve common signal issues within your home. Designed for use in homes measuring over 3,000 sq. ft., this signal amplifier/repeater will boost signal strength throughout your house and optimize the reliability of your X10 systems. If your home has less than optimum coupling, let the X10 Signal Coupler Repeater boost your signals.


What's Included

  • 1x - X10 Signal Coupler Repeater
  • More Info

    The X10 Signal Coupler Repeater is recommended for homes measuring over 3,000 sq. ft. and for homes in which a number of devices are installed. When devices such as televisions, computer gear, or anything with a complex power supply are plugged in, there is a good chance that those devices will load down or absorb the X10 signals. If you have a home smaller in square footage but you employ a greater number of electronic devices, then stepping up to the X10 Signal Amplifier / Repeater is a good idea.

    Can I install it myself?
    If you have ever replaced a broken circuit breaker, then you have the experience needed to install the X10 Signal Amplifier / Repeater. You will need two dedicated 15-amp circuit breakers (available at a home improvement center). The National Electric Code requires that the amplifier / repeater have its own circuit breakers. If you have more than one electrical panel, the amplifier/repeater would 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 for him to mount and wire the X10 Signal Amplifier / Repeater.

    How does it work?
    The X10 Signal Coupler Repeater provides the same functions as the signal bridge but it regenerates the X10 signal and blasts it out both legs of electricity at the same time. Provided there is at least 100mV of incoming signal, this unit will boost the outgoing signal to over 5 volts depending on the impedance of the home. A status LED will blink when X10 signals are detected and repeated to let you know it's operational.

    Ready for 3-phase service
    The X10 Signal Coupler Repeater can work on three-phase (120/208 VAC) electrical service, commonly found in commercial apartments, and condominiums. In split-phase installations, commonly found in single family homes, one of the wires will be capped off and unused.

    I wish the prices would come down on these things. You simply cannot expect X10 to work well without it. If it was cheaper, more people would buy them and have a better opinion of X10. If you really want X10 to work well in your house, get one or expect random performance. If you are just starting out with X10, this should be very high on your list of things to buy.

    I got this unit to help push the Insteon signals through my crusty built and wired in 1918 cabin electrical system. I had poor results at first because of poor wire quality from my PowerLink Modem to the electrical panel. I solved the problem by placing the PowerLink Modem at a Receptacle very close to the electrical panel and running an Ethernet cable to a nearby Ethernet switch. I now have very strong signals to and from my insteon devices on both sides of the panel. I even get reliable signal at my shop which is over 500 feet from my home!

    Item did not solve my x10 receiver performance issues.
    RYAN -- severna park, MD   9/9/2011
    The repeater did not work reliably for me. The red LED would come on when the repeater sensed an X10 signal, but the "boosted" repeated signal never seemed to make it to my x10 devices. Maybe it is because I do have a lot of electronics plugged into various outlets (who doesn't?).

    Works like they said it would. Now all my X-10 units work even in pole barn 300 ft. away from house. Fast shipping. will order from here again. Very good service.
    T. E. Dilores -- redmond, WA   7/25/2011
    Product worked fantastic and solved the communications problem I was having - highly recommended over the passive 'signal bridge' or 'SignalLink' that plugged in line with the dryer.
    TYRONE -- dallas, GA   7/22/2011
    Great solution to signal problems
    ERIK -- seattle, WA   7/18/2011
    This turns out to be a useless product to me. Some signals are mirrored correctly. Others which worked without the repeater, no longer work when it is plugged in.

    Great Price. Fast Shipping
    SPIFFY -- layton, UT   6/16/2011
    prompt shipping, item arrived as described, in good condition.

    Exactly what my X-10 system needed for compatibility with Insteon. I have used X-10 Home Automation extensively for over 25 years. I recently added four of the SwitchLinc 2476D Dimmers to replace some old Leviton 6381-U Inductive Dimmers that strobed when dimmed with the new LED replacement flood lamps we installed. The ActiveHome Pro software in conjunction with the CM15A computer interface refused to communicate with the 2476D dimmers. The house panel was already equipped with a Leviton 6299 passive signal bridge / phase coupler. I tried using the BoosterLinc 4827 Plug-In Signal Booster with mixed success. I replaced the 6299 passive device with the 4820X and now everything works perfectly including the Insteon SwitchLinc 2476D dimmers. Thanks to Scott in tech support for his patience in helping me work through this solution. Good job!

    This was installed on a 3 phase system and works great. It solved the erratic behavior of the system.
    GERARD -- phoenix, AZ   5/17/2011
    It Died after 1 month
    ROBERT -- shingle springs, CA   5/1/2011
    Solved some intermittent X10 communication problems due to long power line runs.
    JOE -- sarasota, FL   4/23/2011
    The original unit did not respond to x10 signals. A second unit did not respond either! I returned both for credit excepting the original shipping and handling fee. Zero stars for product. Evidently I can not submit zero stars so I had to mark one star to be able to submit my comments.
    ROBERT -- murray, UT   2/7/2011
    First unit was defective and return process was excellent.
    JAMES -- valencia, CA   2/2/2011
    Works Great. ordering and shipping were great.

    Easy to install. So far, works fine. Ed

    Easy to install and works great. A must have for a good system.
    ALVIN -- kennesaw, GA   1/29/2011
    Completely solved the issue with X10 wall modules not responding to commands for my control module.
