escod5am – co 500ppm duct transmitter current output with com
Carlo Gavazzi ESCOD5AM is a duct-mounted electrochemical carbon monoxide transmitter with a 0–500 ppm measuring range, 4–20 mA analogue output and RS485 Modbus communication for HVAC and building automation applications.
Why Choose the Carlo Gavazzi ESCOD5AM Carbon Monoxide Duct Transmitter?
The Carlo Gavazzi ESCOD5AM is a professional duct-mounted carbon monoxide (CO) transmitter designed for continuous air-quality monitoring in HVAC, ventilation and building automation systems. It combines an electrochemical carbon monoxide sensing element with a standard analogue current output and digital communication for flexible integration into modern control systems.
The ESCOD5AM measures carbon monoxide concentrations across a 0–500 ppm range and provides a standard 4–20 mA analogue current output. It also incorporates RS485 Modbus communication, allowing measurement data to be integrated with compatible building management systems, HVAC controllers and industrial automation networks.
Designed specifically for air-duct mounting, the ESCOD5AM operates from 8–35 V DC or 12–30 V AC and uses an M12 plug for electrical connection. Its plastic transmitter housing provides IP65 protection, while the sensing element is rated IP20, making the unit a practical solution for fixed ventilation and environmental monitoring installations.

Reliable Carbon Monoxide Monitoring for HVAC and Building Automation
Carbon monoxide monitoring is important in ventilation systems serving areas where combustion processes, vehicles or other potential CO sources are present. The ESCOD5AM continuously measures carbon monoxide concentration within an air duct and converts the measurement into a standard 4–20 mA signal for compatible monitoring and control equipment.
In addition to its analogue output, integrated RS485 Modbus communication enables CO measurements to be incorporated into networked building management and automation systems. This combination makes the ESCOD5AM suitable for installations requiring both conventional analogue signalling and digital communication from a single duct-mounted transmitter.
Typical Applications
- HVAC carbon monoxide monitoring.
- Ventilation and air-handling systems.
- Building management systems.
- Car park and garage ventilation systems.
- Commercial and industrial building ventilation.
- Environmental air-quality monitoring.
- Building and industrial automation systems.
