Introduction

The products from the H01-H03 family are reliable RS485 signal hubs made to work with the variable transmission speeds. They allow flexible branching of 1:3 interface while simultaneously providing protection for the attached devices thanks to internal 3 kV/DC galvanic isolation. Additionally, dedicated EMC protections will improve transmission quality and limit the impact of interference typical for an industrial environment.
