This product is an industrial 8-channel USB to RS485 isolated converter with a rail-mount case, features the original CH348L chip and built-in protection circuits such as power isolation, ADI magnetical isolation and TVS. This converter is easier to operate due to its fully automatic transceiver circuit with no delay. Boasting characteristics of fast communication, stability, reliability, and safety, it is an ideal choice for various industrial control devices and applications with high communication requirements.

Features
  • Supports USB to 8CH RS485, convenient for expanding multiple RS485 industrial serial devices
  • Supports direct power supply via Type-C port, with reserved 5V–36V DC wide voltage screw terminal for auxiliary power input
  • Onboard unibody power supply isolation, provides stable isolated voltage
  • Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
  • Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic
  • Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock proof performance
  • Built-in 120R terminal resistor on the RS485 ports, configurable via jumper for flexible switching
  • LEDs for indicating the power, device configuration status and transceiver status
  • Rail-mount case design, support stackable combination, easy to install and safer to use
  • Supports multiple operating systems: macOS, Linux, Android, Windows 11/10/8.1/8/7
