ACI A/CO2-R2 Room CO2 Sensor
Overview
The A/CO2-R2 is a wall-mounted carbon dioxide sensor designed for indoor air quality monitoring and demand control ventilation. It features a dual-channel Non-Dispersive Infrared (NDIR) sensor for high accuracy and long-term stability in commercial environments. The device supports multiple field-selectable output signals including 0-5 VDC, 0-10 VDC, and 4-20 mA to interface with building automation systems.
Why Choose This Part
This sensor features an Automatic Baseline Correction (ABC) algorithm to mitigate long-term drift, ensuring reliable 0 to 2,000 ppm measurements with +/- 3 percent accuracy. Its wide input voltage range of 16.5 to 40 VDC and polarity protection provide significant installation flexibility and robustness against wiring errors.
Applications
Getting Started
Installation requires mounting the ABS plastic enclosure to a standard junction box and selecting the desired output signal via internal jumpers. Connect the sensor to a 24 VAC/VDC power source and wire the analog output to a PLC or building controller's high-impedance analog input. Periodic field calibration is recommended using NIST traceable gas if required by local building codes.
