Insteon DIN Rail Constantly Disconnected

[daveman]

I was hoping to get some help here. I have an Insteon Din Rail On/Off Switch that seems to disconnect after it turns on. I'm able to manually turn it off using the On/Off button on the Din Rail device and then switch it ON from the Java UD Admin Console, but then I can't turn it off and the device becomes "disconnected." Any ideas of what I should try? I have an eisy connected to a PLM. I already tried factory resetting the Din Rail device and re-linking it, but this is still happening even after re-adding it to my system. Any help would be appreciated. Thanks!

What happens if the load is disconnected?  And what is the load in question?  
 

turns on, but can’t turn off is almost always caused by the load generating electrical noise.

On but not off. Does sound like a noisy or signal sucker load. I have had a few over the years.

The load goes to a DIN Rail low voltage unit that powers some landscape lighting. It has worked in the past and this just started happening. I wonder if I need to restart my PLM or something. Should I try disconnecting the Load and seeing if that makes a difference?

Yes definitely test the module without the load, and/or a plain load, like an incandescent light bulb. 
 

Characteristics of the low voltage transformer may have changed as it aged.   and/or it’s always generated some noise but not enough to be a problem. Then something else you’ve added recently has added to that and pushed the electrical noise over the limit.  It’s also possibly that the DIN rail module itself has had some component fail, but I think that’s less likely.  
 

As I mentioned in my first reply, and @Brian H echo’d, when I module turns on reliably but won’t turn off, the problem is almost always noise caused by the load itself.   The load is off and not generating noise, the ON command will work fine, once the load is on and generating noise the OFF command can no longer be heard by the module.
