Product Description
The NFBU200-S serves as a high-reliability hardware foundation for the Yokogawa CENTUM VP distributed control system. This standard-type base module is designed to provide efficient power distribution and stable communication between I/O modules and the Field Control Station (FCS).
It features a rugged 35 mm DIN rail-mounted chassis, enabling seamless integration into industrial control cabinets while maintaining a high-density footprint suitable for demanding process automation environments.
The backplane incorporates a duplexed SB Bus architecture (with Vnet/IP interface support), ensuring uninterrupted internal communication even if one communication path fails. The hardware platform supports flexible power configurations, allowing installation of either single or redundant power supply modules to meet different system availability requirements.

Application and Integration
The NFBU200-S is widely deployed in continuous process industries such as petrochemical, water treatment, and power generation. It serves as the physical interface platform where field signals are processed through I/O modules and transmitted to higher-level control networks.
Its duplex SB Bus design and redundant power capability make it ideal for high-availability control systems that require minimal downtime and stable long-term operation.
Frequently Asked Questions
What is the difference between single and duplex CPU module support on this base?
A single CPU configuration supports up to 8 I/O modules. When duplexed CPUs are installed for high availability, slot allocation and power constraints limit the maximum I/O module count to 6.
Does the NFBU200-S support hot-swapping?
Yes. The CENTUM VP architecture allows hot replacement of I/O and power modules without shutting down the entire station, provided redundancy is properly configured.
