RS232 Male Port To RS485/422 Active Digital isolated Converter

This RS232 Male To RS485/422 Converter features the SP3232EEN and SP485EEN chips, which provide fast, stable, and reliable communication. It is designed with built-in galvanic isolation, providing protection against lightning, electrostatic discharges, and other electrical interferences, making it an ideal solution for industrial control equipment and projects demanding high communication integrity.

It supports transmission rates from 300 to 921600bps without requiring an additional power supply for isolated terminals. The device integrates unibody power supply isolation for stable voltage, digital signal isolation to reduce interference, and a transient voltage suppressor (TVS) to mitigate surge and spike voltages, providing enhanced circuit protection. Additional safety features include onboard self-recovery fuses and protection diodes that maintain stable current and voltage outputs while offering over-current and over-voltage protection to improve overall shock resistance.

We also have the same converter with a female port in our store
