Product Description

Key features

  • Connecting Modbus devices to the ZigBee network
  • Using Modbus/RTU protocol and RS485 interface
  • Routing function
  • RF power 1mW
  • External antenna

How it works

The Bridge has the main function to connect through a ZigBee network one or more Modbus slave devices equipped with RS485 interface to one of the Gateways of the 4-noks products family. In this way the PLC or PC-SCADA connected to the Gateway can communicate with Modbus slave devices eliminating wire installation. This channel is completely transparent.
Furthermore it can be a repeater and a “parent” device for battery powered sensors.
