Waveshare Industrial-grade Isolated 8-ch RS485 Hub, Rail-mount Support, Wide Baud Rate Range

Introducing the Waveshare Industrial-grade Isolated 8-ch RS485 Hub, featuring rail-mount support and a wide baud rate range. The RS485-HUB-8P is an industrial-grade isolated RS485 hub designed to expand 8-ch RS485 slave ports via a 1-ch RS485 master port. It facilitates relay, extension, and isolation functions within RS485 networks and includes screw terminals for power input.

With its rail-mount case design, installation is convenient and cost-effective. This hub is well-suited for various applications including data acquisition, IoT gateway implementation, safety & security IoT solutions, and intelligent instrument monitoring. Compliant with the RS485 Standard, it ensures compatibility and reliability in industrial settings.

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, 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 center) is required, this RS485 hub can effectively isolate the connection interference between multiple RS485.
