ZigBee – ModBus RS485 ZR-BR-485-EM – Bridge

The ZigBee ZR-BR-485-EM Bridge mainly works connecting through the ZigBee network one or more third party ModBus devices with RS485 interface to any gateway among the ones of the 4-noks range. Thus, the PLC or the PC-SCADA connected to the Gateway can exchange information with the third party ModBus devices without the need of a wired connection. The channel prepared in this way is completely transparent.
Moreover, it can work as repeater and as “father” device for battery powered sensors.
