I'm new here and kind of 'invited' to say something about PLCBUS power usage, so here it goes
I have lots of PLCBUS appliance modules and my measurements show me the following numbers:
No load attached:
An appliance module uses an average of 0.3W while it's OFF.
When you change it to ON, this changes to 1.5W.
OFF stays the same, still 0.3W
ON: a bit harder to measure, but it looks like it's still below 2W.
So in normal operation you could say that a PLCBUS module uses 0.3W extra in OFF and 1.5W extra while ON.
I made a picture of the power monitor to prove this, but I'm not allowed to post links here, sorry about that.
Well, a link can be found in my guestbook at www dot hekkers dot net somewhere....
Hope this answers your questions,
