LORDWORLD RS232 to RS485 Isolated Converter Development Board

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.
