esco2w2a – co2 2000ppm wall transmitter current output
Carlo Gavazzi ESCO2W2A is a wall-mounted NDIR carbon dioxide transmitter with a 0–2000 ppm measuring range, 4–20 mA analogue output and 12–36 V DC or 24 V AC supply for HVAC and building automation applications.
Why Choose the Carlo Gavazzi ESCO2W2A CO2 Wall Transmitter?
The Carlo Gavazzi ESCO2W2A is a compact wall-mounted carbon dioxide (CO2) transmitter designed for indoor air quality monitoring, HVAC control and building automation applications. As part of the Carlo Gavazzi ESCO2 series, it uses non-dispersive infrared (NDIR) sensing technology to provide reliable measurement of carbon dioxide concentration in occupied indoor environments.
The ESCO2W2A measures CO2 concentrations across a 0–2000 ppm range and converts the measured value into a standard 4–20 mA analogue current output. This industry-standard signal enables straightforward integration with compatible HVAC controllers, PLCs, building management systems and environmental monitoring equipment.
Designed for convenient wall mounting, the transmitter features a compact plastic enclosure measuring approximately 80 × 80 × 38 mm. It operates from a 12–36 V DC or 24 V AC supply, incorporates an M12 plug connection and provides IP54 protection for indoor building services and environmental monitoring installations.

Reliable CO2 Monitoring for HVAC and Building Automation
Carbon dioxide concentration is an important indicator for occupancy-related indoor air quality and can be used to control ventilation according to actual demand. The ESCO2W2A continuously measures CO2 concentration and converts the reading into a standard 4–20 mA signal that can be monitored by compatible building and HVAC control equipment.
By incorporating the ESCO2W2A into a demand-controlled ventilation system, controllers can adjust fans, dampers and air-handling equipment in response to changing CO2 levels. This can help maintain comfortable indoor conditions while reducing unnecessary ventilation and supporting more energy-efficient building operation.
Typical Applications
- Indoor air quality monitoring.
- Demand-controlled ventilation systems.
- HVAC control and monitoring.
- Building management systems.
- Offices and commercial buildings.
- Schools, meeting rooms and public buildings.
- Building automation and environmental control systems.
