escow3am – co 300ppm wall transmitter current output
Carlo Gavazzi ESCOW3AM is a wall-mounted electrochemical carbon monoxide transmitter with a 0–300 ppm measuring range, 4–20 mA analogue output and RS485 Modbus communication for building and environmental monitoring systems.
Why Choose the Carlo Gavazzi ESCOW3AM CO Wall Transmitter?
The Carlo Gavazzi ESCOW3AM is a wall-mounted carbon monoxide transmitter designed for continuous CO monitoring in building automation, ventilation and environmental control applications. It uses an electrochemical carbon monoxide sensing element to measure CO concentrations within occupied and monitored indoor environments.
The ESCOW3AM provides a 0–300 ppm carbon monoxide measuring range with a standard 4–20 mA analogue current output. Integrated RS485 Modbus communication provides an additional digital interface, allowing measurement data to be incorporated into compatible building management and automation systems.
Designed for wall mounting, the ESCOW3AM operates from an 8–35 V DC or 12–30 V AC supply. Its IP65 plastic housing, IP20 sensing element and 0–50 °C operating temperature range make it a practical solution for fixed carbon monoxide monitoring in commercial, industrial and building-services installations.
