Product Description
Overview
The Yokogawa AAI143-H50/A4S10 is a high-performance 16-channel analog input module designed for current signal acquisition in process automation systems. Supporting 4-20 mA input, it provides reliable data exchange with Field Control Stations (FCS) and is compatible with dual-redundant configurations. The module integrates HART communication, enabling digital variable reading from transmitters and valve positioners alongside conventional analog signals.
This module supports both 2-wire and 4-wire transmitter configurations, which can be set individually per channel using configuration pins. It is designed for robust industrial use, ensuring high accuracy and stability even under varying environmental conditions.
