Both the Appliance and Lamp Modules have a Local Control Sensing Circuit. The Appliance Module also uses this sensing circuit to detect if the mechanical relay is on or off.
Most devices connected to them will not react to this very low current. Some devices like LED bulbs use so little current, even the small sensing current keep them partially glowing. This current is also what caused some CFL bulbs to pulse when off and some to even turn back on by triggering the local control sensing.
The devices you mentioned should be fine. The small current should not be enough to have them try and turn on or run at a very reduced voltage. On the coffee maker. If it has a Neon Bulb 'On Indicator' there is a small chance it may glow dimly but no harm there either.
Rough measurements I made. Old LM465 1.56 ma AC and 0.16 ma DC; soft start LM465 0.36 ma AC no DC current.
AM486 Old style 2.37 ma AC and 1.69 ma DC. New version AM486 X10 calls CFL friendly .33 ma AC.
Thanks!
Actually I think you answered this question for me on another post quite awhile ago, but I had forgotten all about it. It was when I had a device that converted any computer monitor into a TV, and that was plugged into a power bar which was plugged into an appliance module, and it kept turning back on after I turned it off.
That TV device got fried! I'm guessing now it may have had to do with the appliance module.
I've also been having a problem with swann security cameras that are plugged into appliance modules. Every so often they just fail to show any picture at all and I have to unplug the appliance module from the power and plug it back in and then the picture comes back.
And one of these swann cameras I had to return to the manufacturer because the picture went out of focus, but I think that may have more to do with the cable, at least that's what I'm hoping it is.
