LORDWORLD RS232 to RS485 Isolated Converter Development Board

SKU CH-7DZR-DFWG5

Converts RS232 signals to balanced differential RS485 with onboard ADI magnetic isolation, TVS surge protection and integrated power isolation at 300-115200bps

  • Converts RS232 signals to balanced differential RS485 for reliable industrial communication
  • Stable transmission across 300 to 115200bps supports diverse legacy and modern equipment
  • Integrated power isolation delivers stable voltage without an external supply for the isolated terminal
  • ADI magnetic isolation provides signal separation with strong anti-interference and low power consumption
  • Onboard TVS suppresses surge and transient spikes while protecting against electrostatic discharge

Isolated RS232 to RS485 Converter Board

This development board converts RS232 signals into balanced differential RS485 signals with built-in isolation. It is designed for engineers and makers integrating legacy serial equipment into industrial or IoT networks. The onboard ADI magnetic isolation and unibody power supply isolation remove the need for an external isolated power source. It suits projects requiring reliable long-distance serial communication.

Check Your Serial Port And Baud Requirements

Verify that your host device provides a standard RS232 interface with compatible signal levels before ordering. The converter operates at baud rates from 300 to 115200bps, so confirm your application works within this range. Ensure the target RS485 bus uses the same asynchronous protocol and that wiring supports differential signalling. No extra power supply is needed for the isolated terminal.

Integrates Directly Into Serial Bus Wiring

The board sits between an RS232 port and an RS485 bus, drawing power from the RS232 side to supply the isolated section. Onboard TVS protection suppresses surge and transient spike voltages on the line. Magnetic isolation adds strong anti-interference performance for noisy environments. This frees the designer from adding separate isolation modules or external power regulators.

Questions about this item

Does the board come with cables or a separate power supply for the RS-232 and RS-485 sides?

The board includes onboard power-supply isolation so the isolated terminal needs no extra supply; cables for the DB-9 and terminal-block connectors are not included and must be sourced separately.

Should I choose a different model if I need baud rates above 115200 bps?

This converter supports 300 to 115200 bps only; if your application requires higher rates you will need a different device.

What does the 115200 bps rating mean when the board is installed in a real machine?

It is the maximum stable asynchronous throughput the isolated link can sustain between the RS-232 and RS-485 ports under normal conditions.
