1. USB to 8CH RS485 Industrialgrade insulated converter, supporting USB to 8CH RS485 for convenient expansion of multiple RS485 serial devices. Enables simultaneous and independent communication for each channel. 2. Supports direct power supply via TypeC port, with a reserved 5V36V DC widevoltage screw terminal for auxiliary power input. Compatible with Win11/10/8.1/8/7, macOS, Linux, Android, etc. 3. Features onboard unibody power supply insulation for stable isolated voltage. Integrated unibody digital isolation ensures signal isolation, reliability, strong antiinterference, and low power consumption. 4. Equipped with onboard TVS (Transient Voltage Suppressor) to effectively suppress surge voltage and transient peak voltage in the circuit, offering faderesistant and antistatic protection. 5. Builtin selfrecovery fuse and protection diodes ensure stable current/voltage output, providing overcurrent/overvoltage protection and improved shock resistance. 6. Includes a builtin 120Ω terminal resistor on RS485 connectors, configurable via jumpers for flexible switching. LEDs indicate power, device configuration status, and transceiver status. Supports wall mounting, rail mounting, and stackable installation. 7. Transmission distance up to 1.2 km—converts USB signals into 8 balanced differential RS485 signals with stable transmission rates. The RS485 transmission range is approximately 1.2 km, while the USB range is about 5 meters.
