Product Description
The NFPW444-10-S2 is a high-performance DC-to-DC power conversion module for Yokogawa STARDOM FCN and FCJ autonomous controllers. It converts 24 V DC input into a stable 5.1 V DC output for the backplane and connected I/O modules. The S2 hardware revision indicates an improved internal design optimized for thermal efficiency and component longevity. The module supports dual-redundant (duplex) operation with hot-swap capability, ensuring continuous operation in mission-critical industrial environments.
