Introduction

C05 - C08 is a family of products that are reliable M-Bus electrical standard converters. They enable communication in master mode with many (60-400) simultaneously connected slave devices and can work as M-Bus repeaters letting to broaden the range of the interface, while simultaneously making the quality better and supporting the safety of the communication. Dedicated EMC integrated circuits guarantee improved connection quality by limiting the impact of interference typical for an industrial environment.

Frame ground FG

Electronic circuits are constantly prone to electrostatic discharge ESD. Redisage 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.

Frame Ground FG connection reference drawing is provided below.

If earth ground is not available FG can be left floating or it can be connected with the power supply GND.
