Raxmolo USB-RS485 Isolated Converter CH344L Chip | No external power needed for isolated end; stable isolation voltage for multiple devices.

Key features

• The onboard self-recovery fuse and protection diode can stable output of current and voltage, prevent overcurrent and overvoltage, and improve impact resistance.
• The 4-way isolated RS485 interface can be expanded through USB, which is convenient for users to expand access to multiple RS485 industrial serial port devices.
• The onboard integrated power isolation can provide stable isolation voltage, and no additional power supply is required for the isolation end.
• CH344L chip, high-speed communication is stable, reliable and compatible.
• The built-in RS485 output terminal 120R resistor can be enabled through the dip switch, and the switching is flexible.
