PD Sensor
PHOTODIODE SENSOR
WITH REMOTE ADJUSTMENTS
4 Wire, External Power w/ Fixed Output Range
The PD Sensor is a four wire, analog photosensor which provides a light level input into PLCBuildings S-Series, LC3X lighting controls and other building automation systems. The PD has six models which are used in different ocations in and around buildings in addition to specialty applications. Indoor sensors are used in offi ces and classrooms. Two types of sensors detect light for outdoor control; low range sign and site lighting and high range sensors for contrast lighting. Atrium sensors measure light in lobbies. Skylight sensors read the ambient light available in warehouse skylights. Other sensors include a high range outdoor sensor for tunnel daytime lighting control. Each sensor has a different range and focus of the light being measured.
