About this item
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.
Industrial Isolation Protection--Built-in optoelectronic isolation circuit, can effectively isolate RS485 master and sub devices, provides multiple protections such as anti-electrostatic, light-ningproof & anti-surge, which is suitable for the industrial environment with high reliability and safety requirements. Supports 35mm standard guide rail, with rail-mount buckle, easy to install.
