The Yokogawa AAR145-S00 S1 is a high-density, 16-channel analog input module designed for the CENTUM series control systems. This module is specifically engineered to process RTD (Resistance Temperature Detector) and Potentiometer (POT) signals, providing isolated inputs for reliable data acquisition in industrial process control environments.
This module is widely used in process automation systems where precise temperature monitoring or position feedback is required. Typical applications include thermal management systems, valve position monitoring, and critical process measurement loops within the Yokogawa CENTUM distributed control system architecture.
