The Telaire T5100 Series CO2 Transmitter (part number T5100-LED) is a wall-mount carbon dioxide transmitter for the building controls market, intended to work with building automation systems to control fresh air supply. Demand-controlled ventilation driven by CO2 measurement prevents the energy loss caused by over-ventilation while maintaining indoor air quality, which makes the Telaire T5100 Series CO2 Transmitter suited to spaces such as conference rooms, classrooms and meeting halls.

Measurement for the Telaire T5100 Series CO2 Transmitter uses a patented non-dispersive infrared (NDIR) absorption sensing engine with gold-plated optics, covering 0 to 2000 ppm with an accuracy of plus or minus 30 ppm or 3% of the reading shown, whichever is higher. The patented ABC Logic self-calibration algorithm corrects for drift and removes the need for manual calibration in most applications, and Telaire provides a lifetime CO2 calibration guarantee when ABC Logic is used. Sensors are shipped factory calibrated. Signal update is every 5 seconds, with a warm-up of under 2 minutes for operation and 10 minutes for maximum accuracy.

Output of the Telaire T5100 Series CO2 Transmitter is field selectable as voltage (0 to 5 V or 0 to 10 V, jumper selectable) or current (4 to 20 mA), though not both at once. Power is 18 to 30 VAC RMS or 18 to 42 VDC, with typical consumption of 0.7 W. The Telaire T5100 Series CO2 Transmitter is CE, RoHS, REACH and WEEE compliant and operates from 0 to 50 degrees C.
