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.

Technical Specifications

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.
