Introduction

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

Frame Ground FG

Electronic circuits are constantly prone to electrostatic discharge ESD.
Rediisage Electronics modules feature a design for the frame ground terminal block FG.
The frame ground provides a path for bypassing ESD, which provides enhanced static protection ESD abilities and ensures the module is more reliable.

Connecting FG terminal block to the earth ground will bypass the ESD disturbances outside the device so will provide a better level of protection against ESD.
