Waveshare 34620 USB To RS485 C Industrial Grade Isolated Bidirectional Converter

1. The USB TO RS485 (C) is an industrial-grade, isolated, bidirectional USB-to-RS485 converter based on the FT232RNL chip. It converts a host's USB port into an RS485 differential bus interface and is suitable for applications such as industrial control, device debugging, Modbus device communication, and long-distance serial communication. 2. Supports USB to RS485 communication
3. Uses the original FT232RNL chip; offers high-speed, stable, and reliable communication with excellent compatibility
4. Features an onboard isolated transceiver with integrated electrical isolation and ESD protection, effectively enhancing communication stability and interference resistance in industrial environments
5. Includes onboard TVS (Transient Voltage Suppressor) to effectively suppress surge voltages and transient voltage spikes; provides lightning and ESD protection
6. Equipped with a resettable fuse and protection diodes to ensure stable current and voltage output, prevent overcurrent and overvoltage, and improve surge resistance
7. Features 3 onboard LED indicators for easy monitoring of power and signal transmission/reception status
