Product Description
The NFPW444-11 is a high-reliability DC-to-DC power regulation module designed for the Yokogawa STARDOM FCN and FCN-RTU autonomous controller series. It converts a 24 V DC supply into a stable 5.1 V DC logic power output for the system backplane and connected I/O modules. As an updated revision of the NFPW444 family, the “-11” version typically incorporates enhanced component durability and protective measures for operation in harsh or corrosive industrial environments.

Technical FAQ
Q: What is the difference between NFPW444-10 and NFPW444-11?
A: The NFPW444-11 is a later hardware revision of the NFPW444-10. While functionally interchangeable in most systems, the -11 version generally features updated components and enhanced environmental or EMC compliance, such as ISA G3 coating.
Q: Can the NFPW444-11 be used in solar-powered RTU installations?
A: Yes. Its native 24 V DC input and high efficiency make it well suited for FCN-RTU sites powered by batteries and solar arrays, commonly used in remote monitoring applications.
