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
Why Choose This Converter
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.
