Carbon Dioxide Sensor
PCT-CO2-R
Product information
The PCT-CO2 indoor CO2 sensor is suited for all types of building controllers and can offer accurate and reliable measurement results. The sensor makes use of an imported CO2 detecting module and detects CO2 in the air using the non-dispersive infrared (NDIR) principle. It has good selectivity, does not require oxygen, and has a long life. It has a steady and reliable power supply, as well as multiple output signals with outstanding stability and anti-interference.
Technical criterion
A. High sensitivity, high resolution, and low power consumption
B. Digital signal noise reduction with high stability
C. Simple to operate, with a jumper to select linear output. 0-10V or 4-20mA
D. BACnet MS/TP or Modbus RTU communication output
E. Quick response time, temperature correction, high stability, and extended service life

Wiring diagram
Precautions & Installation
A. The sensor should be put in a position that is reasonably stationary.
B. Connect the sensor to the controller once all other electronics and tests have been completed.
C. Check to see if the power supply voltage is within the rated range.
D. To avoid the control wires passing through regions with high magnetism and noise, use screened cables to connect; do not hang heavy things on the wires.
E. To minimize saturated condensation, the sensor should not be in direct contact with water and should not be exposed. To avoid any harm, non-professionals are not permitted to disassemble electronic components and sensors.
