Rail-mount TTL To RS232 (B)

Galvanic isolated Serial Port Converter

 
 
 
Features at a glance
  • Compatible with TTL/RS232 standard, converting the TTL signal into RS232 signal, supports full-duplex communication
  • Compatible with 3.3V ~ 5V TTL signal level, provides anti-reverse and over-voltage protection for power supply interface
  • Onboard unibody power supply isolation, provides stable isolated voltage and 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 suppresses surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic
  • Onboard protection diodes, ensure the current/voltage stable outputs, provide over-current/over-voltage protection, improve shock proof performance
  • Onboard power supply screw terminal, allows 3.3V~5V DC input
  • Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective
