Self-Contained Ambient Light Transmitters MAS Series

Self-Contained Ambient Light Transmitters

 

The PLC-Multipoint MAS Series sensors are microprocessor-based light monitors that measure ambient light levels. They provide an analog DC signal to various microprocessors and energy management systems. The sensor is powered by 24 VDC and provides a 4-20 mA analog signal over 2 wires. The MAS Series can be set to a range of 0 to 10,000 fc. It comes in many styles of housing, including indoor, outdoor, atrium and skylight. The MAS Series sensor's range can be changed with the MAS-CAL from up to 4000 feet away.
