CDT-MOD-2000 CO2 TRANSMITTER, WALL MOUNTED

FEATURES Communication:RS-485 Modbus (RTU) Accuracy: CO2: ±40 ppm + 2 % of reading, DC model: 75 ppm or 10 % of reading (whichever is greater)

CDT-MOD-2000

Multifunctional CO2 transmitters for building automation systems that use Modbus serial communication protocol

CDT series air quality transmitters are engineered for building automation systems in the HVAC/R industry.

The CDT series measures carbon dioxide (CO2) utilizing the industry standard NDIR measurement principle,

and temperature (T). Optional relative humidity (rH) measurement is also available in the same device.

 

CDT series devices include:

• Modbus communication for each measurement parameter (CO2, rH, T)

• One analog output for selected measurement: voltage (0/2–10 V) or current (4–20 mA)

•  2″ x 3″ touchscreen display

• Optional relay output
