These units are particularly loud when they are cycled on and off.

Is this normal?

Are there any brands that are silent?

Thanks,

Every module i've ever used has a rather audible "click" to it..

This is due to the relay inside the unit.. I don't know of any X10 modules that use a solid state relay.

Yes, they are all pretty load unless you step up and spend about $25. Then you can get some that reduce the noise about 80% - not totally silent though.

Thanks for the reply. I checked out the URL you listed. Could only find the 'SuperSocket Outlet Wall Module' at $9.99. Can you supply the part number of the $25 dollar module you referred to?

Also, on your home page 'Couplers, Repeaters, Filters, etc.' doesn't go any where.

I don't really understand why these relays have to be so freakin' loud anyway?????? remember those old big marantz stereo receivers. they had pretty beefy relays (seems like if I remember right they were around 6-10 amps) for their switched outlets. the top backs of the units were open for ventilation and they weren't particlularily loud. the x10 units are absolutely ridiculous. I've got about 10 scattered through the living room, kitchen, TV room, etc, all set to the same code for various xmas decorations. it sounds like a 2x4 split when they all throw. if the dogs are napping, they wake up, head to the door, and start barking.
