Yokogawa NFSBT02 S1 Autonomous Controller – STARDOM FCN/FCJ Series
When a remote pumping station loses its communication link to the central DCS, production doesn’t stop — it can’t afford to. Without a capable autonomous controller on-site, operators face uncontrolled shutdowns, safety interlocks that fail to execute, and costly emergency dispatches to unmanned facilities. The Yokogawa NFSBT02 S1 Autonomous Controller is engineered precisely for these mission-critical moments: it continues executing its control logic independently, protecting assets and maintaining process stability even when the network goes dark.
The NFSBT02 S1 occupies a strategic position within Yokogawa’s STARDOM FCN/FCJ platform — a field-proven autonomous controller family trusted across oil & gas pipelines, water treatment networks, and power utilities worldwide. As a core CPU/communication module of the FCN series, the NFSBT02 S1 delivers IEC 61131-3 compliant programming, deterministic scan-cycle execution, and robust Ethernet-based connectivity in a compact, DIN-rail-mountable form factor. Its global installed base spans thousands of remote and distributed control nodes across six continents, making it one of the most widely deployed autonomous controllers in the process automation industry.
