Applications
C01 - MBus10 Converter to RS232
C02 - MBus10 Converter with active RS232 interface
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 FG can be left floating or it can be connected with power supply GND.
