So, you want to run a low voltage to remotely turn on an outlet? Well, then this product is ALMOST what you need. By default, if you plug in the MP-15, its outlets are already ON, not off. When you supply the low voltage signal, the outlets turn off. This is opposite of how the Amazon product title (... Remote Turn-on from Momentary or Maintained Contact Switches) is written. Very misleading. It is opposite of what I need. I even called product support at Furman and inquired whether there might possibly be internal jumpers that could control the sensing polarity, but, alas, they were too short-sighted to think of such a need.
Internally, there is a Song Chuan 832A-1A-C-12VDC relay. That is a normally open (NO) relay. What is really needed is a single-pole, double throw (SPDT) relay with a jumper or switch to allow you to pick the polarity. I'm planning on modifying my MP-15 and swapping in a 832A-1C-C-12VDC relay and rewiring it to get the polarity I need. Lucky that I am skilled with a soldering iron...
