Carlo Gavazzi ESCO2D5AM is a duct-mounted NDIR CO2 transmitter with a 0–5000 ppm measuring range, 4–20 mA current output and RS485 Modbus communication for HVAC and building automation systems.
The Carlo Gavazzi ESCO2D5AM is a reliable duct-mounted carbon dioxide (CO2) transmitter designed for continuous indoor air quality monitoring in HVAC, ventilation and building automation systems. As part of the Carlo Gavazzi ESCO2 environmental sensor series, it uses non-dispersive infrared (NDIR) sensing technology to provide stable CO2 concentration measurement for demand-controlled ventilation and environmental monitoring applications.
The ESCO2D5AM provides a wide 0–5000 ppm CO2 measuring range together with a standard 4–20 mA analogue current output. Integrated RS485 Modbus communication provides an additional digital interface for connection to building management systems, PLCs and compatible automation controllers, allowing CO2 measurements to be incorporated into modern networked control systems.
Designed specifically for air duct mounting, the ESCO2D5AM enables representative CO2 measurements directly within ventilation and air-handling systems. It operates from a 12–36 V DC or 24 V AC supply and combines an IP65 transmitter housing with an M12 electrical connection for practical installation in commercial and industrial HVAC applications.
Carbon dioxide concentration is an important indicator of indoor air quality and occupancy levels in commercial buildings. The Carlo Gavazzi ESCO2D5AM continuously measures CO2 within an air duct, allowing ventilation controllers and building management systems to adjust airflow according to measured conditions rather than relying solely on fixed ventilation schedules.
Its 4–20 mA current output provides straightforward integration with conventional analogue control systems, while RS485 Modbus communication enables digital transmission of measurement data to compatible automation networks. This combination makes the ESCO2D5AM suitable for both traditional HVAC control architectures and modern intelligent building management systems.
