This Industrial USB to 4-Port RS485 Converter transforms a standard USB interface into four isolated RS485 communication channels. Powered directly from a single USB port (no external PSU required), this device delivers reliable serial connectivity in industrial and automation applications.

Key Highlights:

  • USB-powered — plug-and-play installation
  • 4 isolated RS485 serial channels
  • High-level protection against electrical hazards
  • Supports multi-point communication networks
  • Works with standard serial software and drivers

Industrial-Grade Performance and voltage protection

  • 3 kV galvanic isolation between USB and RS485 interfaces — protects host devices from voltage surges.
  • 6 kV three-level lightning protection safeguards RS485 communication lines from transient high-energy events (IEC61000-4-5 standard).
  • USB port has built-in TVS protection (±15 kV air, ±8 kV contact).
  • Built for tough environments with operating temperatures from -40°C to +85°C, ensuring reliable operation in extreme conditions.

Plug & Play
No external power supply or driver modifications required — simply install the drivers and connect via USB and begin communication. Supports Windows environments natively.

Features at a Glance

  • Full-speed USB 2.0 interface (500 kbps – 12 Mbps) compatible with USB v2.0 devices.
  • Simulates a standard serial port allowing legacy serial software to interface seamlessly.
  • Up to 2 Mbps communication speed on RS485 lines.
  • Communication distances up to 3 km (depending on baud rate).
  • Supports large networks with up to 128 nodes (and more, depending on load).
  • Multiple LED indicators for power status and per-port Rx/Tx activity.

Typical Applications

  • Industrial automation systems
  • PLC and sensor networks
  • Building management systems
  • Remote data acquisition equipment
  • Multi-node serial communication networks

This converter is ideal for environments that require robust, interference-resistant communication and long-distance fieldbus connections.
