The RS232 DB9 Female to RS485/422 Converter is an industrial-grade solution for seamless communication in demanding environments. With a robust rail-mount case design, this converter ensures durability and protection through features like built-in power isolation, ADI magnetical isolation, and TVS diode. The onboard SP3232EEN and SP485EEN chips facilitate zero-delay automatic transmission conversion, enabling faster communication speeds with enhanced stability, reliability, and safety. Its user-friendly design makes it easy to operate, meeting the needs of scenarios requiring high communication standards. Whether wall-mounted or rail-mounted, this converter is a reliable choice for industrial applications, ensuring efficient and secure RS232 to RS485/422 conversion.

  • Onboard SP3232EEN and SP485EEN chips. Fast communication, stable and reliable, better compatibility.
  • Stable transmission at the rate of 300~921600bps.
  • 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, and low power consumption.
  • Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic.
  • Onboard self-recovery fuse and protection diodes, ensure the current/voltage stable outputs, provide over-current/over-voltage proof, and improve shockproof performance.
  • Onboard 15KV ESD isolation protection and 600W lightning proof & anti-surge protection.
  • Onboard 120R terminal resistor on the RS485/RS422 interface, disabled by default, configurable by jumper.
  • Onboard power supply screw terminal, allows 5V~36V DC wide-range input.
  • 3 LEDs for indicating the power and transceiver status.
  • Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective.
