Resideo c7232a1016 Non-dispersive Infrared Ndir Carbon Dioxide CO2 Sensor Wall Mount 24V

Product Description

The Resideo C7232A1016 is a wall-mount, non-dispersive infrared (NDIR) carbon dioxide sensor designed for use in commercial and residential HVAC ventilation systems. HVAC technicians and building automation professionals rely on CO2 sensors like this one to measure indoor air quality and trigger ventilation responses when carbon dioxide levels climb above acceptable thresholds. The C7232A1016 connects to HVAC controllers to help determine when fresh outdoor air needs to be introduced into a space, making it a core component in demand-controlled ventilation (DCV) strategies.

Non-dispersive infrared technology is the industry standard for accurate, stable CO2 measurement. Unlike electrochemical sensors, NDIR sensors use infrared light absorption to detect CO2 concentration without consuming the gas being measured. This makes them highly reliable over long service intervals and well-suited for continuous monitoring applications in occupied spaces such as offices, classrooms, retail environments, and multi-family buildings.

The C7232A1016 operates on 24V power, which is the standard control voltage used across most commercial HVAC systems. It features a normally open single-pole single-throw (SPST) relay output, allowing it to integrate directly with air handling units, economizers, or building automation systems. The sensor has a warm-up and response timing of 60 seconds, giving it a fast and reliable reading cycle. Its operating temperature range of 32 degrees Fahrenheit to 122 degrees Fahrenheit makes it suitable for a wide variety of installation environments. Wall mounting ensures accurate sampling of room-level air quality where occupants are present.

• Non-dispersive infrared (NDIR) sensing technology for accurate, long-term CO2 measurement
