This is an industrial USB to RS485 converter featuring the original CH344L chip, with built-in protection circuits including power isolation, ADI magnetic isolation, and TVS. Its aluminum alloy case design ensures durability. The converter is easy to operate, offers automatic transmission, and delivers fast communication, stability, reliability, and safety. It is ideal for industrial devices and applications with high demands.

Key features
  • Adopts original CH344L chip, high-speed communication, stable and reliable, better compatibility.
  • Supports USB to 4-ch isolated RS485, convenient for expanding multiple RS485 industrial serial devices.
  • Onboard unibody power isolation, provides stable isolation voltage, no additional power supply is required at the isolated side.
  • Onboard unibody digital isolation, support signal isolation, with better reliability, stronger anti-interference ability, and lower power consumption.
  • Onboard TVS (Transient Voltage Suppressor) to effectively suppress surge voltage and transient spike voltage in circuits, lightning-proof protection, and anti-static protection.
  • Onboard self-resetting fuses and protection diodes ensure stable current and voltage output, prevent overcurrent and overvoltage, and improve shock resistance.
  • Built-in RS485 output terminal 120R, can be enabled by dip switches, and flexible switching.
  • The transmission distance is about 1.2km for RS485 and about 5 meters for USB.
  • 10× external LEDs for power, device configuration status, and signaling status.
  • Aluminium alloy enclosure with sand blasting and anodic oxidation.
  • Supports wall-mount and rail-mount installation, rigid and nice-looking, easy to install.
