Carbon Dioxide Sensor with Relay Option The CO2-VEN Series monitors carbon dioxide levels in industrial and living environments from 0 to 2,000 ppm. They offer the installation flexibility of adding analog relative humidity and temperature sensors in a single wall-mounted enclosure. The CO2-VEN offers multiple analog outputs of 4 to 20 mA, 0 to 5 VDC, and 0 to 10 VDC. The concentration of carbon dioxide is measured using a Single Beam/Non-Dispersive Infrared (NDIR) Absorption sensing method. The carbon dioxide transmitter is also equipped with a patented ABC Logic™ (Automatic Background Calibration) software. This software virtually eliminates the need for manual calibration in applications where the indoor carbon dioxide level drops to outside levels during unoccupied periods. The ABC Logic™ will not work properly in applications where the space is left unoccupied for less than 4 hours a day or where there are industrial sources of carbon dioxide. Units ending with the REL-2K or REL-5K suffixes offer relay outputs. This allows fresh air into a ventilated space to meet regulated standards, providing immediate energy savings. Relay control can be used to control fresh air when no building automation system is available. The factory default setting is at 800 ppm but can be easily changed to 1,000, 1,200, or 1,500 ppm at the unit. Customizable settings are available via UIP software. In addition, the REL-5K suffix models feature conformal coating for added moisture protection. Analog temperature outputs are limited to 0 to 5 VDC, 0 to 10 VDC, and 4 to 20 mA for the relay option versions. The A/CO2-VEN Series is covered by ACI's Two (2) Year Limited Warranty. The warranty can be found in the front of ACI's Sensors & Transmitters catalog, as well as on ACI's web site, www.workaci.com.
