LNK-XT Network Extender Peripheral Device

    Key Features

  • » 
    Extends transmission range of the Modbus® network
  • » 
    Boosts communication signal strength
  • » 
    Power LED indicator
  • » 
    Standard Modbus® RS-485 RTU protocol
  • » 
    Standard water / dust tight, corrosion resistant enclosure (drip proof)
The LNK-XT Network Extender peripheral device works as a signal booster allowing transmission and receipt of gas readings over a larger total area. It extends the range of the Modbus® communication network allowing a longer distance between the Controller and the gas detectors. The micro controller quickly passes Modbus information packets  from the master side of the LNK-XT to the extension side, seamlessly without interruption. 
Multiple LNK-XT peripheral devices may be required depending on the size of the application. An LNK-XT is recommended every 2000 ft, approximately every 32 transmitters.
Ideal for large applications to create an efficient distribution network of specialized gas detection devices that can communicate over a large distances.
