Re: X-10 Appliance modules- more than just a relay?

Hi Nigel,

Yep....just the leakage current used for local sensing.
If you do the mod to disable local sensing it should stop it.

Do a search for the link coz I cant remember where I got the info, but it
only takes about 5 minutes to do.

BTW. Discovered over Christmas that the leakage on a UK Wall swithc is
enought to light a set of Christmas Tree lights to about 30% brightness
even
when off. That's some leakage.

I've got an X-10 query (gasp!) for someone who knows about the internals of
an appliance modules... I've got one AM12U, which I assumed switched the
load with a relay (from the clicking sound!).  However, we bought one of
the little Electroluminescent night lights at the weekend, and it glows
dimly even when the appliance module is switched off, round about 1/2
normal brightness.

I realise the nightlight doesn't need much power (about 200mW if my
calculations are right), but if it's just a relay in the appliance module,
it shouldn't even get that.

Is it just leakage in some noise suppression components across the relay
contacts that is lighting it (<1mA)?

It's not particularly critical, I'm just curious, but if someone doesn't
know the answer I'll have to disassemble it myself...

Nigel
