Product Details
Product Description
The NFPW444-50 is a high-performance DC-to-DC power conversion module specifically engineered for the Yokogawa STARDOM autonomous controller platform. This unit serves as the primary energy source for the Field Control Node (FCN) backplane, converting a standard 24 V DC industrial supply into a highly stabilized +5.1 V DC output required for CPU logic and internal bus communication. Designed for mission-critical reliability, the NFPW442-50 ensures deterministic performance in environments where AC power is unavailable or where battery-backed DC systems are utilized for maximum uptime.
As a "Standard Type" (non-explosion protected) component, the NFPW444-50 is intended for general industrial areas. It features advanced voltage regulation to maintain consistent output even during supply fluctuations, protecting sensitive downstream I/O modules from electrical stress and data corruption.

Operational Applications
The NFPW444-50 is primarily deployed in STARDOM FCN-RTU architectures found in remote oil and gas production sites, solar-powered monitoring stations, and maritime automation systems. It is the ideal choice for modular controller racks that require a direct DC interface to local battery arrays or DC UPS systems, ensuring a seamless power transition during primary utility failure.
Technical FAQ
How does the NFPW444-50 handle voltage dips in the 24V supply?
The module is rated for a wide input range down to 21.6 V DC. This tolerance allows the NFPW444-50 to maintain a stable +5.1 V DC logic supply even during moderate battery discharge or voltage drops caused by high-current loads elsewhere on the same DC loop.
Is this module compatible with redundant power configurations?
Yes. In STARDOM FCN enclosures with dual power slots, two NFPW444-50 modules can be installed to operate in a parallel redundant mode. If one module or its power source fails, the secondary unit assumes the full load without causing a system reset or CPU interruption.

Tech & Buying Guide
Evolving SCADA System Architectures in Industrial Automation
A robust Supervisory Control and Data Acquisition (SCADA) system serves as the heartbeat of modern industrial operations. Understanding SCADA system architecture is vital for engineers designing efficient control systems. These architectures have evolved from isolated, monolithic structures to highly interconnected, networked ecosystems. Choosing the right design requires balancing data visibility, processing power, and long-term scalability requirements.
Choosing the Right Controller: PLC vs. Motion Controller in Industrial Automation
Selecting the optimal control architecture is a foundational decision in industrial automation. Engineers must frequently choose between a Programmable Logic Controller (PLC) and a dedicated Motion Controller. While both systems manage machinery, their underlying design philosophies differ significantly, impacting performance, scalability, and system integration.
Mastering PLC Power Supply Architectures and Operating Voltages
Selecting the correct operating voltage is a critical step in designing reliable industrial automation systems. Whether you are working with a compact PLC or a large-scale DCS, your power architecture dictates the system's longevity. In this guide, we explore the standard voltage ranges and power distribution strategies required to maintain stable factory automation operations.
