This Industrial USB to RS485 Bidirectional Converter is equipped with the high-performance original CH343G chip, ensuring stable and fast data communication. Thanks to its built-in multi-layer protection circuits, it is ideal for use in harsh industrial environments where reliability and safety are critical.

Features At A Glance

  • Support USB to RS485 bidirectional conversion
  • Fast communication, stable and reliable, better compatibility
  • Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic
  • Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock proof performance
  • 3 LEDs for indicating the power and transceiver status
