Yokogawa NFBU200-S16 S1 Base Module – 16-Slot I/O Base Unit for STARDOM FCN/FCJ DCS
Imagine a critical process control loop suddenly losing communication between the controller and its field I/O modules. Alarms cascade, operators scramble, and production halts — all because the foundational base unit that physically and electrically interconnects every I/O card in the rack has failed or is unavailable. The Yokogawa NFBU200-S16 S1 is that indispensable backbone: without it, no I/O module in the STARDOM FCN/FCJ architecture can function, communicate, or be hot-swapped safely.
The NFBU200-S16 S1 is the 16-slot base unit within Yokogawa’s STARDOM FCN/FCJ Series — a compact, open-network DCS platform widely deployed in oil & gas, chemical, water treatment, and power generation facilities worldwide. As the S1 generation base unit, it provides the physical mounting rail, internal backplane bus, and power distribution backbone for up to 16 I/O or function modules, making it the structural and electrical heart of every STARDOM FCN rack assembly. Its global installed base across thousands of process plants underscores its role as a mission-critical component in modern distributed control architectures.
