#1 GEWINNER

  • Adopting original FT4232HL chip, RS232 adopts DB9 female interface, high-speed communication, stable, reliable and good compatibility. 4 isolated RS232 interfaces can be extended via USB, which is convenient for users to extend access to multiple RS232 industrial serial devices. Compatible with Mac/Linux/Android/Windows 11/10/8.1/8/7 and other systems
  • On-board integrated power isolation, can provide stable isolation voltage. On-board integrated digital isolation provides signal isolation with high reliability, strong anti-interference and low power consumption
  • On-board TVS (transient voltage suppression tube), can effectively suppress the surge voltage and transient spike voltage in the circuit, anti-static. On-board terminal extra power supply interface, support 5~36V DC wide voltage power supply
  • On-board self-recovery fuses and protection diodes to ensure stable current and voltage output, prevent overcurrent and overvoltage, and improve shock resistance
  • 9 external LED indicators, easy to check the power supply, device configuration status and signal transmitting/receiving status. Aluminum alloy case with oxidized and frosted finish, more solid and durable
