esco2w5a – co2 5000ppm wall transmitter current output

Why Choose the Carlo Gavazzi ESCO2W5A CO2 Wall Transmitter?

The Carlo Gavazzi ESCO2W5A is a wall-mounted carbon dioxide transmitter designed for indoor air-quality monitoring, HVAC control and building automation applications. It uses non-dispersive infrared (NDIR) sensing technology to provide reliable continuous measurement of carbon dioxide levels within occupied indoor environments.

With a 0–5000 ppm CO2 measuring range, the ESCO2W5A is suitable for applications requiring a wider measurement range than standard 2000 ppm building sensors. A standard 4–20 mA analogue output enables straightforward integration with compatible HVAC controllers, PLC analogue inputs and building management systems.

The ESCO2W5A is designed for wall mounting and operates from a 12–36 V DC or 24 V AC supply. This model is supplied without Modbus communication, providing a straightforward analogue solution for CO2 monitoring and demand-controlled ventilation applications.

Reliable CO2 Monitoring for Building Automation

Carbon dioxide concentration is an important parameter when monitoring indoor air quality and managing ventilation in occupied buildings. The Carlo Gavazzi ESCO2W5A provides continuous CO2 measurement over an extended 5000 ppm range, allowing compatible control systems to monitor changing environmental conditions and respond accordingly.

Its standard 4–20 mA current output provides a robust industrial signal for connection to HVAC controllers, PLCs and building management systems. This makes the ESCO2W5A particularly suitable for applications where a simple analogue interface is preferred for ventilation control and environmental monitoring.

Typical Applications

• Indoor air-quality monitoring.
• Demand-controlled ventilation systems.
• HVAC control and monitoring.
• Building management systems.
• Commercial and office buildings.
• Educational and public facilities.
• Ventilation and air-handling systems.
• Industrial environmental monitoring.
