Overview

The BMT-F870 series optoelectronic isolation 485 converter (RS485/RS232 to 5-way RS485) hub is an RS485 bus splitting hub (HUB) designed to meet the requirements of RS485 systems in complex electromagnetic field environments. It provides RS485 bus connections, allowing users to easily improve the RS485 bus structure, segment network segments, and enhance communication reliability. In order to ensure the safety and reliability of data communication, the RS485 interface adopts magnetic coupling technology to prevent lightning surges from entering the converter and equipment. It is equipped with built-in optoelectronic isolators and 600W surge protection circuits.
