Waveshare USB to RS485/422 Industrial Grade Isolated

Waveshare (23949) USB to RS485/422 Industrial Grade Isolated Converter, Onboard Original FT232RL and SP485EEN, Multiple Protection, Wall and Rail Mounting Support

The converter uses the original FT232RNL and SP485EEN chips and provides stable communication with built-in galvanic isolation, lightning protection and anti-electrostatic protection. Suitable for industrial control devices and/or applications with high communication requirements.

Features:

• Integrated original FT232RL and SP485EEN chip. Fast communication, stable and reliable, better compatibility
  
• Onboard unibody power supply isolation, provides stable isolated voltage, does not require additional power supply for the isolated terminal
  
• Onboard unibody digital isolation, enables signal isolation, high reliability, strong anti-interference, low power consumption
  
• Onboard TVS (Transient Voltage Suppressor), effectively suppresses overvoltages and transient voltage spikes in the circuit, lightning-proof & anti-electrostatic
  
• Integrated self-recovery fuse and protection diodes ensure stable current/voltage outputs, provide overcurrent/overvoltage protection and improve shock resistance
  
• Integrated 15KV ESD isolation protection and 600W lightning-proof & anti-surge protection
  
• Integrated 120R termination resistor on the RS485/RS422 ports, enabled by default, configurable via jumper
  
• 3 LEDs to indicate power supply and transceiver status
  
• Industrial ABS housing design for rail mounting
