It connects an FCN control unit to I\/O extension units through a dedicated SB Bus communication link. This configuration includes an SB Bus T-joint, supporting the connection between repeat modules and the associated bus cable.\u003c\/p\u003e\n\u003ch3\u003eFunction and Communication\u003c\/h3\u003e\n\u003cp\u003eThe NFSB100 repeats serial communication between the FCN control unit and its I\/O extension units. It supports an SB Bus transmission rate of 128 Mbps, with a maximum transmission distance of 8 m per line.\u003c\/p\u003e\n\u003cp\u003eFor systems requiring a duplexed SB Bus, two repeat modules can be installed in each unit.
