esco2w5am – co2 5000ppm wall tx current output with com
Carlo Gavazzi ESCO2W5AM is a wall-mounted NDIR CO2 transmitter with a 0–5000 ppm measuring range, 4–20 mA current output and RS485 Modbus communication for HVAC, indoor air quality and building automation systems.
Why Choose the Carlo Gavazzi ESCO2W5AM CO2 Transmitter?
The Carlo Gavazzi ESCO2W5AM is a reliable wall-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) technology to provide accurate CO2 concentration measurement for demand-controlled ventilation and environmental monitoring applications.
The ESCO2W5AM 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, making the transmitter suitable for both conventional analogue systems and networked building controls.
Designed specifically for wall mounting, the ESCO2W5AM monitors CO2 directly within occupied spaces and controlled indoor environments. It operates from a 12–36 V DC or 24 V AC supply and combines a compact IP54 fire-resistant polycarbonate housing with an included M12 electrical connector for practical installation in commercial and industrial buildings.

Reliable CO2 Monitoring for Building Automation
Carbon dioxide concentration is an important indicator of indoor air quality and occupancy-related ventilation demand. The Carlo Gavazzi ESCO2W5AM continuously monitors CO2 within occupied spaces, allowing HVAC controllers and building management systems to adjust ventilation according to measured conditions rather than relying solely on fixed schedules.
The transmitter combines a standard 4–20 mA current output with RS485 Modbus communication, allowing the same sensor to integrate with conventional analogue control equipment and modern digital building automation networks. Its wall-mounted format and NDIR sensing technology make it particularly suitable for offices, educational facilities, commercial buildings and other occupied environments where reliable CO2 monitoring is required.
Typical Applications
- Indoor air quality monitoring.
- Demand-controlled ventilation systems.
- HVAC control systems.
- Building management systems.
- Commercial offices and public buildings.
- Schools, colleges and educational facilities.
- Environmental control and monitoring systems.
- Greenhouses and agricultural environments.
- Fruit and vegetable storage areas.
