The LS-102 daylighting controller is a single zone, ON/OFF switching device designed to be installed in a closed loop application. A self-contained 24 VDC device with an extended range of 1 to 1400 fc, the LS-102 requires a low voltage power pack to operate. The controller consists of an advanced digital multi-band photosensor, an on-board microcontroller and an LCD display. This photosensor is positioned behind a 100 deg cone that cuts off unwanted light, preventing false triggers.

WattStopper® Switching Photosensor, Automatic Closed Loop, 12/24 VAC/VDC, 7 mA, Daylight Sensor, Environmental Conditions: 35 deg F Operating Temperature, 95% Non-Condensing Relative Humidity, 108 cpm Operating Cycles, Fixture Mounting, Plastic, 2.4 in Dia x 0.7 in D Dimensions
