Carbon Monoxide Sensor
PCT-CO-R
Product description
PCT-CO indoor CO sensor can provide accurate and reliable measurement data, suitable for all kinds of building controllers. The sensor utilizes an imported CO sensing module and uses the principle of non-dispersive infrared (NDIR) to detect CO present in the air. It has good selectivity, no oxygen dependence, and long life. Built-in temperature compensation, equipped with reliable and stable power supply and various output signals with excellent stability and anti-interference.
Technical parameter
A. High sensitivity, high resolution, low power consumption
B. High stability digital signal noise suppression
C. Easy to use, jumper to choose linear output 0-10V or 4-20mA
D. BACnet MS/TP or Modbus RTU communication output
E. Fast response time, temperature compensation, excellent stability, long service life

Wiring diagram
Installation and Precautions
A. The sensor should be installed in a relatively stationary position.
B. After all other electronics and tests are complete, connect the sensor to the controller.
C. Ensure that the power supply voltage is within the allowable rated range.
D. It is recommended to use the screened wires to connect to avoid the control wires going through places with large magnetism and noise; do not hang heavy objects on the wires.
E. The sensor should not be in direct contact with water and should not be exposed to avoid saturation condensation. Non-professionals are not allowed to dismantle electronic components and sensors to avoid possible damage.
