The Telaire T5100-LED is a low-cost, high-performance CO2 transmitter designed for the building controls market. It integrates seamlessly with building automation systems, enabling effective control of fresh air intake to meet regulated standards while providing immediate energy savings through demand-controlled ventilation.

The transmitter features a patented NDIR (Non-Dispersive Infrared) gas sensing engine delivering high accuracy in a compact package. The measurement range is 0 to 2000 ppm with accuracy of 30 ppm or 3% of reading, whichever is higher. Color LEDs in dot mode provide at-a-glance indication of CO2 levels for immediate visual feedback on indoor air quality.

Telaire's patented ABC Logic self-calibration system eliminates the need for manual calibration in most applications and is backed by a lifetime CO2 calibration warranty. The transmitter is available with field-selectable output options including 0-5V, 0-10V, or 4-20 mA for CO2 and temperature.

Installation is simplified with a mounting plate featuring two-piece terminal blocks for quick wiring. A gas permeable, water-resistant diffusion filter protects the sensor from particulate and moisture contamination. A locking screw secures the cover to the mounting bracket for tamper resistance. The modern enclosure design suits a variety of indoor environments. UIP software is available for custom configuration. The T5100-LED is CE, RoHS, REACH, and WEEE compliant.
