esco2w2vm – co2 2000ppm wall tx voltage output with com
Carlo Gavazzi ESCO2W2VM is a wall-mounted NDIR CO2 transmitter with a 0–2000 ppm measuring range, 0–10 V analogue output and RS485 Modbus communication for HVAC and building automation systems.
Why Choose the Carlo Gavazzi ESCO2W2VM CO2 Wall Transmitter?
The Carlo Gavazzi ESCO2W2VM 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 continuous CO2 measurement within occupied spaces.
The ESCO2W2VM provides a 0–2000 ppm CO2 measuring range together with a standard 0–10 V analogue output. This allows straightforward connection to compatible HVAC controllers, PLC analogue inputs and building management systems for ventilation and environmental control.
Integrated RS485 Modbus communication provides an additional digital interface for compatible automation systems. With its compact 80 × 80 × 38 mm wall-mounted housing, 12–36 V DC or 24 V AC supply and IP54 protection, the ESCO2W2VM provides a practical solution for demand-controlled ventilation and indoor CO2 monitoring.
