Description
The RS485-HUB-8P is a robust and isolated RS485 hub designed for industrial applications. It provides the capability to expand 8-channel RS485 slave ports through a single RS485 master port, effectively offering relay, expansion, and isolation functions for RS485 networks. With a convenient screw terminal for power input and a rail-mounted housing design, this product is both easy to install and cost-effective. It finds its utility in various applications, including data collection, IoT gateways, security and safety IoT systems, and intelligent instrument monitoring.
Key Specifications:
- Interface: Complies with RS485 standard.
- Physical interface: RS485 screw terminals.

Primary Function:The RS485-HUB-8P is designed to support relay, expansion, and isolation functions within RS485 networks.
Connection Diagram: You can connect the isolated RS485 master port to your RS485 host device, while the extended 8-channel isolated RS485 port can be connected to various RS485 slave devices, such as RS485 sensors. It effectively manages connections, even in scenarios requiring star connections (with the main station as the center), isolating potential interference between multiple RS485 devices.
Industrial Insulation Protection:This product features a built-in photoelectric isolation protection circuit that effectively separates RS485 master and slave devices. This isolation prevents damage caused by ground potential differences between devices, offering protection against electrostatic discharge, lightning, and surges. It is well-suited for industrial environments with high reliability and safety requirements.
Wide Baud Rate Range:The RS485-HUB-8P supports a broad communication range for baud rates, ranging from 300 to 460800 bps, with self-adaptive capabilities.
Rail Assembly: It can be easily mounted on a 35mm standard guide rail with a rail fixing buckle, ensuring a hassle-free installation process.
