YOKOGAWA AAI143-H50 Analog Input Module

Description

The YOKOGAWA AAI143-H50 Analog Input Module is a high-performance industrial automation component designed to receive and process analog signals from sensors or transmitters. It supports voltage and current input types with selectable input ranges, and provides a 4-20mA output range. Equipped with 16 isolated channels, the module can measure multiple parameters including PH, ORP, DO, EC, TDS, and SDI, making it suitable for diverse industrial monitoring applications.

Key performance specifications include ±0.1% FS accuracy, a response time of less than 0.5 seconds, and a 2500V RMS isolation voltage for enhanced signal integrity and protection. It operates on 24 VDC power with a low 1.5W power consumption, and features an IP67 protection rating for durability in harsh environments. The module uses DIN rail mounting for easy installation, and supports multiple communication protocols including HART, Modbus RTU, and Modbus TCP for seamless system integration and remote control.

The model suffix “H” indicates support for HART digital communication, while “5” means it does not include explosion-proof protection (explosion-proof versions are available with the “-E” suffix). It is compatible with Yokogawa DCS systems such as CENTUM CS 3000 R3, and incorporates a logically independent dual-bus electrical interface that supports interface backup or single-device connection to dual redundant bus systems for improved operational reliability.
