The Yokogawa AAI141-H00/K4A00 is a 16-channel analog input module used in industrial process control systems.

It takes analog signals from field devices and converts them into digital signals for a control system to understand and utilize.

Functionality:

• Analog Input: This module accepts analog signals, typically a 4-20 milliamp (mA) current loop or 1-5 Volt DC signal, from up to 16 sensors or transmitters. These sensors could measure various process variables like pressure, temperature, flow, or level.
• Digital Conversion: The AAI141-H00/K4A00 converts the received analog signals into digital data. This digital data is then transmitted to a control system for processing, monitoring, and control purposes.
