Product Description

Dwyer CDTA-5E000-LCD is a Modbus CO2 detector for indoor air quality monitoring, measuring 0–2000 ppm with 2 min response time. It operates on 10–42 VDC / 10–30 VAC and communicates via RS-485 Modbus RTU or BACnet MS/TP, suitable for HVAC and building automation systems.

Frequently Asked Questions

What is the Dwyer CDTA-5E000-LCD Modbus CO2 detector used for?

The Dwyer CDTA-5E000-LCD is used for indoor air quality monitoring in HVAC and building automation systems. It measures CO2 levels from 0 to 2000 ppm, along with humidity and temperature, and communicates via RS-485 Modbus RTU or BACnet MS/TP to enable demand-controlled ventilation and energy-efficient climate management.

What are the specifications of the Dwyer CDTA-5E000-LCD?

The Dwyer CDTA-5E000-LCD measures CO2 from 0 to 2000 ppm with ±40 ppm ±3% accuracy, humidity from 10 to 95% RH, and temperature from 0 to +50°C. It operates on 10–42 VDC or 10–30 VAC, consumes 1.2 watts peak, and has a 2-minute response time to 99% of step change.

Where to buy the Dwyer CDTA-5E000-LCD in Singapore?
