Product Description
The NFPW444-10 is a dedicated DC-to-DC power conversion module engineered for the Yokogawa STARDOM FCN and FCJ autonomous controller series. It supplies high-current, regulated 5.1 V DC logic power to the system backplane, ensuring stable operation of processor and I/O modules. Designed for mission-critical reliability, the module supports duplexed power architectures, enabling seamless failover and non-disruptive maintenance during live system operation.

Advanced Functionality
The NFPW444-10 integrates Reliability, Availability, and Serviceability (RAS) features, including internal diagnostics and temperature monitoring for early fault detection. Its fanless architecture eliminates mechanical wear components, significantly improving MTBF. The module is also optimized to support FOUNDATION™ Fieldbus H1 segments, making it well suited for modern digital field instrumentation and distributed control architectures.
Technical FAQ
Q: Does this module support hazardous area installations?
A: Standard NFPW444-10 units are intended for general industrial environments. Hazardous area requirements are addressed by the “-E” suffix variant, which provides the necessary explosion protection certifications.
Q: What happens if one power module fails in a duplexed configuration?
A: In a duplexed setup, the remaining NFPW444-10 module immediately assumes the full load without output voltage drop, ensuring uninterrupted operation of the FCN/FCJ controller.
