The Yokogawa AAI135-H00 is an 8-channel analog input module designed for industrial process control systems. It converts signals from analog transmitters (such as those measuring temperature, pressure, or flow) into digital data, enabling integration with distributed control systems (DCS). With high reliability and accuracy, this module plays a crucial role in real-time process monitoring and control, especially in systems requiring redundancy and precise data acquisition.
