        Features:

        • High-Reliability Dual Redundancy Architecture
        • Exclusive SB Bus and E2 Bus Extension Capability
        • Industrial-Grade Ruggedness and Certifications
        The Yokogawa NFBU200-S05 S2 is explicitly engineered to support true hardware duplexing for both power supplies and CPU modules. This industrial-grade design guarantees that any single-component failure—whether a power drop or a processing fault—will trigger a seamless, bumpless transfer to the backup unit, ensuring maximum uptime for continuous production lines.

        As a vital differentiator in large-scale system designs, the Yokogawa NFBU200-S05 S2 is the only long base module in the STARDOM portfolio that fully hosts SB bus repeat modules (NFSB100) alongside E2 bus modules. This permits high-speed inter-unit communication across up to 8 extended chassis, reducing engineering complexity during system expansions.

        Built to withstand harsh, unconditioned field environments, the Yokogawa NFBU200-S05 S2 operates reliably across a wide temperature spectrum of -20°C to +70°C. Backed by universal certifications including CE, CSA, UKCA, and RCM, this chassis delivers superior electromagnetic compatibility and mechanical resilience, preventing signal distortion or structural fatigue.

        The NFBU200-S05 S2 Yokogawa FCN Autonomous Controller Base Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        • High-Availability Fault Isolation: The segregated backplane channels of the Yokogawa NFBU200-S05 S2 prevent localized short circuits in an individual I/O module from corrupting main CPU communication lines.
        • Real-time Power Status Monitoring: Delivers dedicated pathways that allow the controller to independently check status lines on dual-redundant power supplies, ensuring proactive utility warning triggers.
        • Extensive Unit Interconnectivity: Enables deep system monitoring by hosting specialized SB bus repeat modules, which transmit critical hardware diagnostic flags from extension racks to the central controller.
        • Precise Time Synchronization Support: Provides steady internal clock-bus synchronization across all slots on the Yokogawa NFBU200-S05 S2, ensuring precise Sequence of Events (SOE) timestamping.
        • Ultra-Low Thermal Dissipation Profile: Drawing a maximum internal current of only 0.4 A at 5 V DC, the Yokogawa NFBU200-S05 S2 keeps cabinet heat generation to an absolute minimum, extending the lifespan of surrounded electronics.
        • Optimized Space Efficiency (19" Form Factor): Packs a full 10-slot capacity into a tight 132.5 mm high rack frame, freeing up critical cabinet space and minimizing overall control room footprints.
        • Bumpless Module Hot-Swapping: Engineered to drastically reduce Mean Time to Repair (MTTR), allowing support engineers to replace field I/O modules on the active Yokogawa NFBU200-S05 S2 chassis without stopping process loops.
        • Zero-Maintenance Passive Backplane: Lacking active microprocessors or components prone to early degradation, the Yokogawa NFBU200-S05 S2 ensures high mean-time-between-failures (MTBF) and decades of operational life.
        Description
        The Yokogawa NFBU200-S05 S2 is modular controller module. This module boasts rich functionality and high reliability. It supports various modular configurations, including CPU modules, power modules, SB bus repeater modules, and I/O modules.

        The NFBU200-S05 S2 is a high-reliability base module engineered by Yokogawa Electric Corporation, specifically designed as the foundational hardware platform for the FCN-RTU low-power autonomous controller series. 

        As a long-type base module, it serves as the central backbone for integrating CPU modules, power supply units, and additional I/O modules, delivering exceptional scalability, robustness, and low-power performance tailored to harsh industrial environments—particularly in remote or energy-constrained applications such as oil and gas wellheads, pipeline monitoring, and distributed process control systems.

        At the core of the NFBU200-S05 S2’s design is its modular expandability, supporting up to 8 additional I/O modules (when paired with compatible Yokogawa IOM units) via its ten-slot architecture (with two slots reserved exclusively for the CPU module) .

        Technical notes
        Designed as a non-explosion protected basic type for standard rack deployments, the Yokogawa NFBU200-S05 S2 requires the integration of FCN-compatible power modules (e.g., NFPW441/NFPW442) and CPU units to initiate operation. During full duplex CPU and power operation, thermal dissipation guidelines must be precisely calculated based on the specific I/O module load deployed onto the Yokogawa NFBU200-S05 S2 backplane to maintain optimal performance.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        What is the maximum number of I/O modules for the Yokogawa NFBU200-S05 S2?
        This module supports a maximum of 8 I/O modules.
        What are the mounting methods for the Yokogawa NFBU200-S05 S2?
        This module supports 19-inch rack mount.
        Does the Yokogawa NFBU200-S05 S2 support redundancy?
        Yes, this module supports redundancy of the CPU, power supply module, SB bus, and control network.
        How does the Yokogawa NFBU200-S05 S2 allocate physical slots for I/O and communication modules during redundant CPU operations?
        When configuring the Yokogawa NFBU200-S05 S2 for CPU redundancy, Slots 1–2 are designated for the dual NFPW44x power supply modules, while Slots 3–4 host the dual FCN-500 CPU modules. This architectural configuration leaves Slots 5–10 available, enabling you to mount up to 6 high-density I/O or extension modules (such as E2 or SB bus interfaces) directly onto the backplane.
        What firmware or software compatibility requirements should be checked when upgrading to the Yokogawa NFBU200-S05 S2 Style 2 hardware?
        The Yokogawa NFBU200-S05 S2 base module utilizes a passive, highly reliable backplane layout, which means it does not contain onboard active firmware. However, integration requires ensuring that your Logic Designer or Stardom Configurator software supports the specific CPU model (NFCP501/NFCP502) and style version that you plan to seat onto this Yokogawa NFBU200-S05 S2 chassis.
