Waveshare 26681 Industrial Isolated USB to RS232/485 Converter, Original FT4232HL Chip, Supports USB to 2-Channel RS232 + 2-Channel RS232/485, Wall and Rail Mounting Available

Features:

• Uses the original chip FT4232HL, fast communication, stable and reliable, better compatibility.
  
• Supports USB to 2-channel isolated RS232/485 + 2-channel isolated RS232.
  
• Integrated unibody power supply isolation, provides stable isolated voltage, does not require additional power supply for the isolated connection
  
• 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 protection and ESD protection
  
• Built-in self-healing fuse and protection diodes, ensures stable current/voltage outputs, provides overcurrent/overvoltage protection, improves shock resistance
  
• Integrated 120R connection resistor on the RS485 interface, can be activated/deactivated via jumper
  
• 9 LEDs to display power and transceiver status
  
• Industrial-grade metal housing, supports wall and rail mounting, solid and elegant, easy to install
