Product Overview
The Yokogawa NFPW442‑10 S2 is a power supply module designed for Yokogawa’s S2‑bus automation systems, such as CENTUM VP and related control systems. It provides stable 5.1 V DC system power and 24 V DC analog field power to support other modules like I/O, communication, and CPU unités. This module ensures reliable and continuous operation in industrial automation and process control environments.
Redundancy is supported by installing dual modules on the base platform (e.g., NFBU200), enabling high system availability and fail‑safe performance.
