The CDT-MOD-2000 series air quality transmitters are engineered for building automation systems in the HVAC/R industry. The CDTMOD-2000 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. The CDT-MOD-2000 series devices have large touchscreen display making the configuration of the device quick and easy. Configuration is also possible via Modbus network.

The CDT-MOD-2000 series transmitters calibrate themselves automatically using ABCTM logic. The ABCTM logic requires that the space in which the transmitter is used needs to to be unoccupied for four hours per day so that the indoor CO2 concentration drops to the outside level. CDT-MOD-2000-DC is a dual channel model with a measuring channel and a reference channel that makes a continuous comparison and the necessary adjustment accordingly. CDTMOD-2000-DC is also suitable for buildings that are continuously occupied.

CDT-MOD-2000 series devices include:
• Offset feature enabling field calibration 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

Application:
CDT-MOD-2000 series devices are commonly used to monitor:
• CO2 and humidity levels in offices, public spaces, meeting rooms and classrooms
• CO2 levels of return air in ventilation systems
• incoming air and return air humidity levels in ventilation system
• humidity in various industrial applications
• temperatures in HVAC/R environment
• CDT-MOD-2000-DC series devices can also be used in applications where there is a constant source of carbon dioxide present (for example hospitals and greenhouses)
