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.
