WITH 4-20mA Output
2 Wire, Loop Powered, Microprocessor
The MAS is a two wire, microprocessor photosensor which provides a light level input into lighting control and building automation systems. The MAS has four models which are used in different locations in and around a building. The MAS sensors are powered by 24VDC, but can accept from 18 to 30VDC. The output signal is 4-20mA. This robust signal can travel up to 4,000ft without the signal degrading. Both the 4mA and 20mA values are calibrated to factory standard footcandle settings using NIST traceable equipment; Indoor, Outdoor, Atrium and Skylight.
