Product Description
The NFPW444-50 is a DC-to-DC power conversion module designed for the Yokogawa STARDOM FCN and FCJ autonomous controller series. It converts a 24 V DC input into a regulated 5.1 V DC output to supply logic power for processor and I/O modules. As a Basic Type (non-explosion-protected) variant, it offers a cost-effective and reliable power solution for standard industrial environments. Its compact, fanless construction minimizes cabinet footprint while maintaining stable power delivery for critical automation applications.

Operational Highlights
The NFPW444-50 integrates seamlessly into the STARDOM platform and is well suited for sites where 24 V DC is the primary power source, such as battery-backed RTUs and solar-powered remote stations. Although classified as a Basic model, it supports redundant (duplex) power configurations when installed in compatible base units, ensuring that a single power module failure does not interrupt controller operation.
Technical FAQ
Q: What differentiates the NFPW444-50 from explosion-protected versions?
A: The NFPW444-50 is intended for non-hazardous areas and does not include explosion-protection certifications such as those found on “-E” suffix variants (e.g., Zone 2 or Class I Div 2 applications).
Q: Is the NFPW444-50 hot-swappable?
A: Yes. When used in a redundant (duplex) configuration within an FCN base unit, the module can be replaced while the controller remains in operation, allowing maintenance without process interruption.
