Introduction

C01 - C04 family products are reliable M-Bus electrical standard converters. They enable communication in master mode with up to 10 simultaneously connected slave devices. Dedicated EMC integrated circuits guarantee improved connection quality by limiting the impact of interferences typical for an industrial environment.

C03 - MBus10 Converter to RS485

C04 - MBus10 Converter to RS232/RS485 with active RS232 interface

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 ~~availabe~~available FG can be left floating or it can be connected with power supply GND.
