BD series DC voltage sensors are the measuring module that converts the measured DC voltage into the proportional DC current or DC voltage signal according to the optical isolation theory. The input side is highly insulated from the output side.
High accuracy, linearity and integration, small size, simple structure, long-term stability and adaptability to various working conditions. They are widely used for system control and detection of electrical equipment in the power, petroleum, mine, chemical, railway, communication, building automation sectors.

Example of Wiring
As shown in the figure,the input is lac.The output of current output sensor is the current source with common GND while the output of voltage output sensor is the voltage source with common GND.In this example,RL is the user load.If the output is current,the load is up to 400Ω(with 12V power supply) or 800Ω(with 24V power supply). If the output is voltage,the load is 1kΩ or above.
