RS485-HUB-8P is an industrial grade isolated RS485 hub that can expand 8-ch RS485 slave ports through 1-ch RS485 master port, can realize relay, extension and isolation functions of RS485 network, with screw terminal for power input. Rail-mount case design, easy to install, and cost-effective. It is suitable for applications like data acquisition, IoT gateway, safety & security IoT, and intelligent instrument monitoring.

Primary function
Supports RS485 network relay, extension and isolation functions
Connection diagram
The isolated RS485 master port can be connected to the RS485 host device, and the extended 8-ch isolated RS485 port can be connected to various RS485 slave devices, such as RS485 sensors, etc.
Generally the RS485 requires a hand-in-hand connection, if a star connection (master station as the center) is required, this RS485 hub can effectively isolate the connection interference between multiple RS485.
Industrial isolation protection
Built-in photoelectric isolation protection circuit, can effectively isolate RS485 master and slave devices to avoid the damage of ground potential difference between devices, anti-electrostatic, lightningproof & anti-surge, which is suitable for the industrial environment with high reliability and safety requirements.
Wide baud rate range
Supports 300?460800bps wide baud rate communication range (self-adaptive)
Rail-Mount Support
Supports 35mm standard guide rail, with rail-mount buckle, easy to install.
