RS232/422/485/CAN/Profibus Hubs

RS485/422 Hub(Din Rail Mount)

RS485/422 Hub(Din Rail Mount)(BUE-485D-HUB)

BUE-485D-HUB is a type of RS-485 bus division concentrator of high performance. BUE-485D-HUB adopts the unique equipotential differential isolation and bus division concentration technology to effectively such problems as ground potential difference, impedance matching and lightning strike frequently seen in engineering wiring process. Users can easily optimize the RS-485/RS-422 bus structure, divide the network section and improve the communication reliability.

The fault network section shall be isolated in case of lightning strike or equipment faults to ensure the high communication reliability of other network sections. Such performance of BUE-485D-HUB can significantly improve t he reliability of existing RS-485/RS-422 network, and effectively shorten the network maintenance time. Reasonable utilization of BUE-485D-HUB can enable you to design unique RS-485/RS-422 system.
