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.
