Waveshare USB TO 2CH RS485 Industrial Grade Isolated Converter

Waveshare 27646 Industrial-Grade USB to 2CH RS485 Isolation Converter, USB to RS485 Adapter, Built-in Original FT2232HL Chip, Stable and Reliable Communication, Multiple Fuses, Support Wall and Rail Mounting

Features:

• Uses the original chip FT2232HL, fast communication, stable and reliable, better compatibility.
  
• Extends USB to 2CH RS485 and enables simultaneous and independent communication for each channel.
  
• Integrated unibody power supply isolation, provides stable isolated voltage, no additional power supply required for the isolated port.
  
• Integrated unibody digital isolation, enables signal isolation, high reliability, strong anti-interference, low power consumption.
  
• Integrated TVS (Transient Voltage Suppressor) effectively suppresses overvoltages and transient voltage spikes in the circuit, lightning and electrostatic safe.
  
• Integrated 120R terminal resistor on the RS485 ports, configurable via jumper for flexible switching
  
• 3 LEDs to indicate power and transceiver status
  
• Industrial ABS enclosure for rail mounting, small, easy to install and cost-effective
