The MD-10B7 motion detector is designed to control lighting or other electrical devices supplied with 230V AC inside and outside buildings. When motion is detected in the detector's field of view, power is supplied to the receiver for the time specified by the built-in time delay setting. In addition, the device is equipped with a light intensity sensor and a regulator of the highest light intensity, at which the detector will work.

The maximum load of the relay used in the detector is 1200W for a resistive load or 300W for an inductive load.
