BPD-500 Series Low Voltage Daylight Sensor

The BPD-500 series members of the TRANS family are low voltage daylight sensors designed to provide digital and analog output for automatic daylight controls through the connected power pack or panel system.

Overview

The BPD-500 series members of the TRANS family are low voltage daylight sensors designed to provide digital and analog output for automatic daylight controls through the connected power pack or panel system. This closed loop daylight sensors employs a cutting edge digital ambient light sensor (ALS) with an advanced algorithm to constantly measure the ambient light level in the controlled area. When the ambient light level is lower/higher than the set value for a period of time, the sensor will automatically engage/disengage its isolated dry contact output to turn the connected light ON/OFF. In addition to the digital output, the sensor also provides 5 different 0-10V analog output ranges pre-settable via Accu-Set potentiometer to report the local ambient light level in timely basis for BMS control.
