YOKOGAWA NFPW442-50 Power Input Module – CENTUM VP / CS 3000 DCS Power Supply
In a continuous-process plant — whether a refinery, chemical reactor, or power generation facility — an unexpected loss of stable DC power to the field control station (FCS) can cascade into a full process shutdown within seconds. Without a reliable power input module, the entire distributed control system loses its backbone, leaving operators blind and actuators unresponsive. The YOKOGAWA NFPW442-50 Power Input Module is the critical interface that conditions and distributes power to the FCS node cards, ensuring uninterrupted control loop execution 24/7/365.
The NFPW442-50 occupies a foundational role within the YOKOGAWA CENTUM VP and CS 3000 DCS architecture. As part of the NFPW4 power module family, it is engineered to accept a 50 Hz AC input and deliver precisely regulated DC power to the node unit, making it the preferred choice for facilities operating on 50 Hz grid infrastructure across Asia, Europe, the Middle East, and Africa. Its proven track record in tier-1 process industries has made it a globally recognized component in mission-critical automation environments.

Frequently Asked Questions
Q: What is the difference between NFPW442-50 and NFPW442-60?
A: The suffix indicates the rated input frequency. The NFPW442-50 is designed for 50 Hz AC power grids (standard in Asia, Europe, Africa, and most of the Middle East), while the NFPW442-60 is for 60 Hz grids (North America, parts of Latin America, and Japan). Using the wrong frequency variant can cause instability or damage to the module and connected FCS components.
Q: Is the NFPW442-50 compatible with both CENTUM VP and CS 3000?
A: Yes. The NFPW4 power module family is used across both the legacy CENTUM CS 3000 and the current CENTUM VP DCS platforms, making the NFPW442-50 a versatile spare for facilities running either generation of YOKOGAWA DCS.
Q: Can I use the NFPW442-50 in a redundant power configuration?
A: The CENTUM VP FCS supports redundant power supply configurations. Consult your YOKOGAWA system documentation or contact our technical team to confirm the correct redundancy setup for your specific node unit chassis.
Q: Do you supply new or refurbished units?
A: Konmask.com supplies both new OEM stock and professionally inspected surplus units. The condition will be clearly stated in your quotation. All units pass our quality assurance process regardless of condition grade.
