The Industrial USB to 4-Port RS232 Converter is a robust interface adapter designed for industrial environments. It converts a single USB connection into four independent RS232 serial ports, each with high-level electrical protection to ensure reliable performance even under harsh conditions.
Powered directly via USB (no external supply required), after installing the drivers the converter is plug-and-play and compatible with standard serial communication software, making it ideal for expanding legacy or automation systems quickly and easily.
Key Features
Industrial-Grade Protection
- 3 kV galvanic isolation on serial interfaces protects against high voltage surges.
- 6 kV three-level lightning protection meets GB/T17626.5 (IEC61000-4-5) standards.
- Built-in TVS protection on the USB port (±15 kV air discharge / ±8 kV contact discharge).
USB & Serial Connectivity
- Full-speed USB 2.0 interface, compatible with USB v2.0 standards.
- Supports Windows (Win2000 → Win11 32/64-bit).
- Emulates a standard serial device — no driver modification required.
Performance & Reliability
- Four RS232 ports with independent isolation.
- Designed for wide temperature range: -40 °C to +85 °C.
- Low operating current (< 30 mA), USB-powered.
- Rugged construction with MTBF > 100,000 hours.
Typical Applications
Perfect for expanding serial connectivity in:
- Industrial automation systems
- PLC / HMI serial communication
- Sensor / actuator networks
- Test & measurement setups
- Legacy equipment integration
Whether you’re adding ports to a PC or extending control systems in harsh environments, this converter delivers reliable serial connectivity with strong electrical protection.
