Product Description
Overview
The Yokogawa AAI141-S00/A4S00 is a 16-channel analog input module designed for accurate voltage and current measurements in process control applications. Unlike isolated modules, this version features non-isolated channels, making it suitable for applications where channel-to-channel isolation is not required. Its high-speed sampling and robust operating range ensure reliable signal acquisition in standard industrial environments.
This module supports both 4-20 mA current inputs and 1-5 VDC voltage inputs, depending on configuration. It is engineered for straightforward integration with field control systems, providing precise analog input acquisition for monitoring and automation tasks.
