Product Description

Dwyer CO2 detector with Modbus/BACnet connectivity measures indoor air quality across 0–2000 ppm range with 2 min response time. Operates on 10–42 VDC or 10–30 VAC, drawing 1.2 watts peak, for HVAC and building automation applications.

Frequently Asked Questions

What is the Dwyer CDTA-2N000-LCD CO2 detector used for?

The Dwyer CDTA-2N000-LCD CO2 detector measures indoor air quality for HVAC and building automation systems. It monitors carbon dioxide levels from 0–2000 ppm, along with humidity and temperature, using Modbus or BACnet communication to integrate with building management networks.

What are the specifications of the Dwyer CDTA-2N000-LCD?

The Dwyer CDTA-2N000-LCD operates on 10–42 VDC or 10–30 VAC, consuming 1.2 watts peak. It measures CO2 from 0–2000 ppm with ±40 ppm ±3% accuracy, humidity from 10–95% RH, and temperature from 0 to +50°C. Communication is RS-485 Modbus RTU or BACnet MS/TP.

Where to buy the Dwyer CDTA-2N000-LCD in Singapore?

3G Electric supplies the Dwyer CDTA-2N000-LCD CO2 detector to Singapore. We source this Dwyer measurement device and handle logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this HVAC sensor.

How to install the Dwyer CDTA-2N000-LCD CO2 detector?

Install the Dwyer CDTA-2N000-LCD by mounting it in an occupied space away from direct airflow. Set the RS-485 MAC address using the built-in DIP switches, then select Modbus RTU or BACnet MS/TP protocol. Connect power (10–42 VDC or 10–30 VAC) and communication wires per the datasheet.
