This is a simple current sensor. When current flow is detected it closes a set of contacts. SWEET! It took a day or so to assemble it in a box with connectors, wire it, and then install it. After adjusting the SENSITIVITY control, it was dialed in, Now when my AV receiver comes on, it turns the SMPTE Bias Lighting on that's located behind the flatscreen.Exactly what I needed!
