Introduction
The Yokogawa NFDA4S‑00 Analog Input Module is a precision measurement interface designed for modular automation platforms such as Yokogawa STARDOM and FCN/FCJ autonomous controllers. This module acquires and digitizes analog signals from field sensors—including current, voltage, and process instrumentation outputs—while providing stability, accuracy, and electrical isolation. Its flexible design and industrial robustness make it suitable for a wide range of automated process monitoring and control applications.
