Industrial Grade Isolated USB Converter

USB TO RS232/485/TTL

Stable Transmission | Multiple Devices Applicable | Multi-OS Compatible

Features At A Glance
  • Adopt original FT232RL or CH343G inside, fast communicating, stable and reliable, better compatibility

  • Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal

  • 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 & ESD protection

  • Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance

  • Fully automatic transceiver circuit with no delay, ensures the USB port communicates with different interfaces fastly and stably, without interfering each other

  • Onboard TTL serial 3.3V/5V voltage translator, config the TTL level via switch

  • Aluminium alloy enclosure with sand blasting and anodic oxidation, CNC process opening, solid and durable

  • 3 LEDs for indicating the power and transceiver status

  • High quality USB-B and RS232 connectors, smoothly plug/pull
