DNT24
2.4 GHz Frequency Hopping Module

Other top DNT24 Applications

  • Applications requiring direct connections and reporting of sensor data
  • SCADA for monitoring and control
  • Scoreboards and Electronic Sign
  • Industrial Remote Control
  • Energy Management

    The DNT90 has the same form factor and pin out as the DNT24 and can be used for this application in the 900 MHz band.

    Commercial Remote Control with Multiple Inputs and Outputs

    Application Overview

    Safety concerns when operating heavy duty industrial equipment such as blowers, crusher plants, remote gate openers, hoists and other equipment with motors has necessitated the need for remote control of these equipment over sufficient distances. Remote control of these devices also allows for freedom and mobility to operate the machinery in locations where direct wired connections is not possible.

    The key requirements for this application required a radio module with multiple analog / digital inputs / outputs. The other key requirement was battery operation. The machinery also generated lots of noise and hence a FHSS solution (Frequency Hopping Spread Spread) was a must. The DNT24 radio module fully satisfied all the requirements of this application

    Applicable Product Features

    The DNT24 radio module’s Sleep and Interrupt- awake capability allowed for battery operation. The Input/Output binding feature simplified the design effort significantly by not having to add additional software or hardware intelligence. Finally the Frequency Hopping Spread Spectrum technology(FHSS) provides reliable RF communication over large distances. The low cost allows systems to be economically priced and finally the 2.4GHz allows world-wide deployment.
