Waveshare Rail-mount TTL To RS485 Galvanic isolated Converter

Waveshare (23778) Galvanically isolated DIN rail mount converter from TTL to RS485, 600W lightning proof & surge protection, multiple isolation protection

• Compatible with TTL/RS485 standard, converts TTL signal into differential RS485 signal, supports half-duplex communication
  
• Compatible with 3.3V ~ 5V TTL signal level, provides anti-reverse and overvoltage protection for the power supply interface
  
• Integrated power supply isolation, provides stable isolated voltage and 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 overvoltage and transient voltage spikes in the circuit, lightning-proof and anti-electrostatic
  
• Integrated resettable fuse and protection diodes ensure stable current/voltage outputs, provide overcurrent/overvoltage protection and improve shock resistance
  
• Onboard RS485 output terminal with 120R resistor, can be activated/deactivated via switch
  
• Industrial ABS housing design for rail mounting, small, easy to install and cost-effective
