Description

Yokogawa NFAI143‑H00‑ 16‑Channel Isolated HART‑capable Analog Input Module

2. Product Overview

The NFAI143‑H00 is field‑mounted FIO analog input module for Yokogawa CENTUM VP / CS3000 DCS and STARDOM FCN controllers. It receives 4‑20 mA current signals from two‑wire and four‑wire field transmitters, converts analog process signals into digital data for controller processing. Built‑in HART communication enables reading device diagnostics, tag information and calibration data from smart HART instruments over existing signal wiring. Full module‑level galvanic isolation suppresses ground‑loop noise and transient surges. Hot‑swap support allows online replacement without system shutdown. NFAI143‑H00 serves as drop‑in spare for remote FIO cabinets, plant turnaround maintenance and system expansion projects.
