Description:
We are presenting Waveshare Industrial-grade Isolated 8-ch RS485 Hub, Rail-mount Support, and Wide Baud Rate Range. An RS485-HUB-8P is an industrial grade isolated RS485 hub that can expand 8-ch RS485 slave ports through 1-ch RS485 master port and 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, intelligent instrument monitoring., etc. It’s compliant with RS485 Standard.

Features:
- Isolated 8-Ch RS485 Hub: Extends 8-ch RS485 slave ports via 1-ch RS485 master port, with isolation and relay
- Cost-effective
- Supports 35mm, Standard Guide Rail, With Rail-Mount Buckle, Easy To Install.
- Good quality product
- TRANSMISSION MEDIUM: Normal parallel cables/twisted-pair cables
- 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.
- Built-in photoelectric isolation protection circuit can effectively isolate RS485 master and slave devices to avoid the damage of ground potential difference between devices, it 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)
- Generally, the RS485 requires a hand-in-hand connection, if a star connection (master station as the centre) is required, this RS485 hub can effectively isolate the connection interference between multiple RS485.
