Extends 8-ch RS485 slave ports via 1-ch RS485 master port, with isolation and relay
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…

Supports RS485 network relay, extension and isolation functions
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.
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.
Supports 300～460800bps wide baud rate communication range (self-adaptive)
Supports 35mm standard guide rail, with rail-mount buckle, easy to install.
