YOKOGAWA AAI141-H50是横河CENTUM VP、CENTUM CS3000 DCS配套16通道模拟量输入卡件，型号后缀H代表支持HART协议，50为标准非防爆版本。卡件接收现场二线制、四线制变送器4-20mA电流信号，将模拟量转换为数字量上传至FCS现场控制站，支持回路断线检测。

YOKOGAWA AAI141-H50 is a 16-channel analog input module for Yokogawa CENTUM VP and CENTUM CS3000 DCS. Suffix H indicates HART protocol support, and 50 means standard non-explosion-proof type. It receives 4-20mA signals from 2-wire and 4-wire transmitters, converts analog signals to digital data for FCS controller and supports wire break detection.

模块通道之间无隔离，系统侧耐压500V AC 1分钟，支持ESB总线冗余配置，可热插拔维护，搭载24位ADC保证采集精度。适配ANB10S、ANB11S节点机架，是流程工业存量DCS系统高频替换备件。

There is no isolation between channels, with 500V AC 1min dielectric strength on system side. It supports ESB bus redundant configuration and hot swap maintenance. 24-bit ADC ensures high accuracy, and it fits ANB10S, ANB11S node racks, widely used as spare for legacy DCS systems.
