Product Overview

The Yokogawa NFAI141-S00 S2 is a high-precision analog input module designed for seamless integration with the STARDOM autonomous controller and relevant DCS architectures. This module provides 16 channels for capturing essential process data, supporting both standard 4-20 mA current loops and 0-10 V DC voltage signals. Engineered for high-speed data acquisition, the NFAI141-S00 S2 ensures that critical variables such as pressure, temperature, and flow are monitored with superior accuracy. Its compact, rack-mountable design makes it an ideal solution for optimizing cabinet space without compromising on technical performance or industrial-grade reliability.

Technical Characteristics

The NFAI141-S00 S2 is built to handle the rigorous demands of modern process automation through the following technical features:

Dual-Signal Compatibility Each of the 16 channels is configurable to accept either current or voltage inputs. This versatility allows a single module to interface with a mixed variety of field transmitters. The hardware supports 2-wire and 4-wire transmitter connections, which can be easily managed via internal setting pins.

Precision and Speed The module delivers a remarkable full-scale accuracy of ±0.1%, ensuring deterministic control for sensitive process loops. With a rapid 10ms data refresh cycle and a 100ms step response time, it is capable of tracking fast-changing process conditions in real-time, providing the controller with high-fidelity data for instantaneous decision-making.

Robust Power Management Equipped to provide a stable transmitter power supply between 22.8V and 26.4V DC, the NFAI141-S00 S2 maintains signal consistency across a wide array of field devices. Its architecture is rated to handle up to 27mA of input current per channel, offering a wide margin for standard industrial monitoring tasks.

System Reliability While maintaining a high channel density, the module is designed for longevity in industrial environments. It integrates effectively with Yokogawa's diagnostic platforms, allowing for proactive monitoring of the module’s health and the integrity of the connected I/O loops.
