Industrial Isolated USB to 4-ch
RS485 Converter (B)

CH344L | Stable Transmission | Multiple Devices Applicable | Multi-OS Compatible

Features At A Glance
  • Adopts original CH344L chip, fast communicating, stable and reliable, better compatibility
  • Supports USB to 4-ch isolated RS485, convenient for expanding multiple RS485 industrial serial devices
  • 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 proof performance
  • Onboard RS485 output terminal 120R resistors, enabled/disabled via DIP switch
  • 10 LEDs for indicating the power, device configuration status and transceiver status
  • Industrial grade metal case, supports wall-mount & rail-mount installation, solid and beautiful, easy to install
