The Yokogawa NFSB100-S50 is a SB bus repeat module designed for the FCN / FCN-RTU / STARDOM autonomous control system, used to extend and stabilize internal SB bus communication between controllers and distributed I/O stations.
In large industrial automation systems, signal attenuation and distance limitations can affect communication reliability. This module solves that challenge by regenerating and amplifying SB bus signals, ensuring stable data transmission across extended system architectures.
It is widely used in oil & gas, petrochemical plants, power generation facilities, and large SCADA networks, where long-distance distributed control and high system availability are required.
