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

The Dwyer CDTA-5E000-LCD measures indoor CO2 levels from 0–2000 ppm for HVAC and building automation systems. It monitors air quality in commercial and institutional buildings, integrating with Modbus RTU or BACnet MS/TP control networks to optimize ventilation and occupant comfort across Singapore's climate-controlled facilities.

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

This Dwyer CO2 detector operates on 10–42 VDC or 10–30 VAC with 1.2 watts peak consumption. It measures 0–2000 ppm with ±8 ppm/°C accuracy, responds in 2 minutes to 99%, and tolerates 0–50 °C and 10–95% RH. Communication is via RS-485 Modbus RTU or BACnet MS/TP.

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

3G Electric is an authorised Dwyer distributor in Singapore. We stock the CDTA-5E000-LCD (SKU DWY34016) and handle full logistics, customs clearance, and DDP delivery across Singapore and Southeast Asia. Contact us for pricing and lead time.

How do I install and integrate the Dwyer CO2 detector with building automation?

Mount the Dwyer CDTA-5E000-LCD in the occupied zone away from direct drafts or exhaust. Wire the RS-485 Modbus RTU or BACnet MS/TP port to your building management system controller. Supply 10–42 VDC or 10–30 VAC power, confirm network address configuration, and verify CO2 data polling within your automation protocol.
