Description

USR-HUB-S Industrial RS485 RS232 RS422 TTL Hub

USR-HUB-SRS485 HUB

The USR-HUB Series RS485 Hub is a range of industrially isolated devices designed to expand a single RS485/232 master port into multiple RS485 slave ports. It facilitates multi-node expansion on the RS485 bus and provides signal repeating and amplification, ensuring stable industrial data transmission.

RS485 HUB

Multiple Models Available | Lightning/Surge Protection | Optical Isolation

The USR-HUB Series RS485 Hub is a range of industrially isolated devices designed to expand a single RS485/232 master port into multiple RS485 slave ports. It facilitates multi-node expansion on the RS485 bus and provides signal repeating and amplification, ensuring stable industrial data transmission. Featuring reliability, flexible expansion, strong anti-interference capability, and convenient deployment, this hub allows users to quickly integrate it into existing industrial RS485 networks without complex debugging. It offers an efficient communication connectivity solution for distributed industrial equipment and is widely applicable in industrial scenarios such as smart manufacturing, automated production lines, industrial equipment monitoring, smart warehousing, and smart buildings.



2 Key Features

  • RS485 Network Repeater: Signal Amplification
  • Slave Expansion: Cascading Multi-nodes
  • Auto-sensing: Data Flow
  • Serial Port Buffering
  • Custom Communication Protocols


One-Master-Multi-Slave, Expand RS485 Network

  • Implements one-master-to-multi-slave conversion and signal repeating, with isolation and short-circuit protection on both master and slave ports.
  • Each RS485 channel supports up to 128 nodes. No configuration required; plug and play.

Buffered RS485 HUB for Multi-Master-One-Slave
Application

  • Built-in 2KB large-capacity buffer to avoid data collisions caused by simultaneous polling from multiple masters.
  • Supports Modbus RTU, DLT645/698 protocols, and user-defined protocols.


One-Master-Multi-Slave (Buffered) Data Concentrator

  • Built-in polling commands enable automatic polling and data aggregation from multiple slaves, allowing centralized read/write access via the master.
  • New slave addresses and starting register addresses can be remapped to improve communication efficiency.

     Four Interface Types

    • Easily achieve transparent bidirectional conversion between RS232/TTL and RS485/RS422.
    • Industrial-grade isolation ensures stable operation, plug-and-play convenience, and strong anti-interference performance.


    Wide Range of Models, One-Stop Selection

    • 2-port, 4-port, and 8-port interfaces are available to meet your needs.
    • Choose from Repeater, Buffered, or Data Distribution types based on your application.

    Industrial-Grade Quality, Built for Harsh
    Environments

    • Industrial-Grade Quality, Built for Harsh Environments
    • Optical Isolation, Anti-Interference: 2500Vrms high isolation voltage | 500V continuous DC/DC module | stable operation, nosystem crashes.
    • Wide-Voltage Power Supply: DC 9-40V power input, with short-circuit protection
    • Robust Interface Protection: ±15KV ESD protection for RS232 ports, 600W TVS lightning/surge protection per line for RS485 ports, serial ports short-circuit/overcurrent self-recovery

    Superior Quality, Perfected in Every Detail

    • Built-in Indicator Lights for Clear Status Visibility
    • High-Quality Enclosure and Connectors for Robust Durability

    Industry Applications

    The USR-HUB series features extensive versatility and can operate stably in various fields such as production management, rail transit, smart buildings, photovoltaic storage and charging new energy, and intelligent power.

    Product Dimension

    PUSR offers multiple size options, and users can choose the one that suits the actual situation as needed.
