The Yokogawa AAV142 is an advanced analog input module designed for use in distributed control systems (DCS). It serves as a vital interface between analog sensors, such as thermocouples, RTDs, and 4-20mA transmitters, and the control system. This module efficiently acquires analog signals and converts them into digital data for further processing, enabling precise control and monitoring in industrial automation systems.
