Description
Dwyer CDTA-5N000 is a communicating carbon dioxide detector with a temperature range of 32 to 122°F (0 to 50°C). It has a CO2 accuracy of ±40 PPM ±3% of reading 2000 PPM and a response time of 2 min for a 90% step change. It operates on a power requirement of 10-42 VDC / 10-30 VAC and has a 15-year life expectancy for its NDIR sensor. It also features 2-wire RS-485, Modbus ® RTU or BACnet MS/TP communication protocol for output.

Communicating Carbon Dioxide Detector
Features
The Series CDTA and CDTC Communicating Carbon Dioxide Detector combines the function of several room sensors into a single, compact housing
Both the Series CDTA and the CDTC’s parameters include carbon dioxide, temperature, and temperature set point with override while the CDTA also includes a humidity sensor
By having field selectable Modbus® and BACnet Communications, only four wires are needed for power and the communication signal
The communicating detectors can be daisy chained together to further reduce installation cost
In order to reduce the set up time, the RS-485 MAC address is set up using on-board DIP switches
A second set of DIP switches are used to select whether output is Modbus® RTU or BACnet MS/TP communication protocols and to limit access to the set up menu
