Industrial Isolated 4-CH RS485 Hub, Expands 4-CH RS485 Sub Ports Via 1-CH RS485

Industrial grade isolated RS485 hub that can expand 4-ch RS485 sub ports through 1-ch RS485 master port. Supports RS485 network relay, extension and isolation functions, with screw terminal for power input. It is suitable for applications like data acquisition, IoT gateway, safety & security IoT, and intelligent instrument monitoring, etc
The isolated RS485 master port can be connected to the RS485 host device, and the extended 4-ch isolated RS485 port can be connected to various RS485 sub devices, such as RS485 sensors, etc. Supports 300~460800bps Wide Baud Rate Communication Range (self-adaptive)
Network Relay: When RS485 cables exceed 1200 meters or longer distances, signals will attenuate and interference will increase. By using RS485-HUB-4P, the communication distance can be extended
Network Extension: When the host RS485 device needs to connect 4 RS485 sub stations via a star connection, connect the master station to the master port of the RS485-HUB-4P, and connect the slaves to the sub ports of the RS485-HUB-4P. This can prevent interference between RS485 and achieve effective isolation
Network Isolation: Connect one end of the RS485 to the RS485 master port, and the other end to any RS485 sub port. At this point, the RS485 line is effectively isolated, providing protection against lightning strikes and interference. This effectively protects the other end of the RS485 device from being damaged by high voltage and strong current
