DNS-24

Building Automation network Sensor for DSC, DAC, or DVC

The DNS-24 is a smart room sensor that can optimize user comfort while reducing energy consumption. It is a simple to install, and cost effective package for advanced, automated, control. With an LCD display and intuitive pushbutton interface, the DNS-24 communicates over an RS-485 LAN using BACnet™ MS/TP or Delta’s LINKnet protocol. The DNS-24 has multiple sensor options including temperature, humidity, and motion, and a self-calibrating CO2 sensor.

Features

  • Native BACnet firmware
  • BACnet MS/TP or LINKnet communications
  • Multiple built-in sensor options including Temperature, Humidity, CO2, and occupancy
  • Self calibrating CO2 sensor
  • Programmable (via GCL+ over network), LCD display
  • 4 Programmable buttons (via GCL+ over network)
  • Derived Network Addressing (DNA) for simple integration into a standard network architecture
  • Optional terminal block2 for wiring a remote thermistor to the temperature input
  • Service port
  • Firmware upgrade3 and database load/ save over the network
