Technical Functional Summary

The NFAT141-S01 is a high-density analog voltage input module for the Yokogawa STARDOM FCN autonomous controller series. It is designed for 16-channel voltage signal acquisition, commonly used with analytical instruments and specialized transmitters providing 1–5 V DC output signals.

The module provides 16-bit high-resolution data conversion and fast refresh cycles for accurate process monitoring in applications such as oil and gas upstream operations, water treatment facilities, and power generation systems.

Unlike fully isolated multi-channel designs, the NFAT141-S01 uses common-ground channel architecture, making it a cost-effective solution for centralized control cabinet installations.

System Application Scenarios

• High-density voltage signal monitoring from analytical equipment

• Autonomous process control in FCN-500 and FCN-RTU systems

• Redundant data acquisition architectures in critical process loops

Technical FAQ

How is NFAT141-S01 different from NFAI141?
NFAT141-S01 is optimized for voltage inputs (1–5 V), while NFAI141 is typically used for current inputs (4–20 mA). The S01 suffix indicates hardware revision compatibility with newer FCN backplanes.

Can it directly measure 4–20 mA signals?
No. A 250 Ω precision shunt resistor must be used to convert current signals into voltage signals.

Is channel isolation provided?
No. Isolation is provided between field inputs and system logic only. For applications requiring full channel isolation, modules such as NFAI143 are recommended.
