Overview

USB TO 2CH RS485 is an industrial USB to RS485 isolated converter with a rail-mount ABS case design, featuring the original FT2232HL chip, built-in power isolation, ADI magnetic isolation and TVS protection circuit, etc. This converter is easy to operate, with zero-delay automatic transmission and reception conversion, and boasts characteristics such as fast, stable, reliable and safe communication. It is an ideal choice for industrial control equipments and/or applications with high communication requirements.

Features

  • Adopts original FT2232HL chip, fast communication, stable and reliable, better compatibility.
  • Extending USB to 2CH RS485, allows concurrent and independent communication for each channel.
  • 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 & anti-electrostatic.
  • Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock proof performance.
  • Built-in 120R terminal resistor on the RS485 ports, configurable via jumper for flexible switching.
  • 3 LEDs for indicating the power and transceiver status.
  • Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective.
