Product Overview

The Yokogawa NFBU200-015 serves as the high-density structural and electrical foundation for the STARDOM FCN-500 autonomous controller and CENTUM VP distributed control systems. This expansive base module provides 15 vertical slots, allowing for massive I/O scaling within a single 19-inch rack footprint. It manages critical communication via integrated SB and E2 buses while distributing 24V DC power to all installed CPU, power supply, and I/O modules. Engineered for high-availability process automation, the NFBU200-015 supports duplexed power configurations to eliminate single points of failure in mission-critical oil, gas, and power applications.

Condition: 100% Brand New Original.

Engineering Advantages

Unmatched I/O Density: The 15-slot architecture significantly increases the number of I/O points available per rack meter. This high-density design allows engineers to consolidate control logic, reducing the total number of required cabinets and minimizing the physical footprint in crowded offshore platforms or containerized substations.
Dual-Bus Communication Integrity: The backplane incorporates redundant SB (System Bus) and E2 bus pathways. This ensures that even if one communication line experiences interference or a hardware fault, the controller maintains seamless data exchange with the field I/O modules, preventing process interruptions.
Redundant Power Distribution: The NFBU200-015 accommodates dual power supply modules. It automatically load-shares and provides failover protection; if one power unit fails, the backplane instantly draws current from the secondary source without resetting the installed CPU or dropping I/O signals.
Ruggedized Polycarbonate Construction: The housing utilizes reinforced, industrial-grade polycarbonate. This material resists chemical corrosion and provides high dielectric strength, protecting the sensitive internal bus traces from the harsh atmospheric conditions often found in chemical processing plants.

FAQs

Q: Can I use the NFBU200-015 with N-IO modules?

A: The NFBU200-015 specifically targets the FIO (Field I/O) family, such as the ADV, NFAI, and NFAF series used in STARDOM and CENTUM VP. While it shares the FIO standard, always verify compatibility with your specific CPU model (e.g., NFCP501) for bus addressing limits.

Q: Does this baseplate require separate grounding?

A: Yes. To ensure maximum EMI (Electromagnetic Interference) protection and safety, you must connect the dedicated grounding terminal on the NFBU200-015 to the cabinet’s functional earth bar using the shortest possible path.

Q: Is the 15-slot layout compatible with standard 19-inch cabinets?

A: Yes. At approximately 480 mm in width, the NFBU200-015 fits perfectly into standard 19-inch racks. It also includes mounting holes for 35 mm DIN rail installation for non-rack-mount industrial enclosures.

Q: What happens if I leave slots empty?

A: Empty slots do not affect the operation of the bus. However, for environmental protection and optimal airflow, Yokogawa recommends using blank filler plates to prevent dust accumulation on the backplane connectors.
