The Yokogawa AAI143-H50/A4S00 is an analog input module engineered for integration into Yokogawa's control systems such as CENTUM VP or ProSafe-RS. This module acquires analog signals from field sensors (e.g., pressure transmitters, temperature sensors) with high precision, supporting input types including 4-20 mA, 0-10 V, and thermocouple/RTD signals. It features channel-to-channel isolation to prevent signal interference, built-in diagnostics for real-time monitoring, and robust construction for operation in harsh industrial environments. The module complies with international safety standards (e.g., SIL 2/3 for safety applications) and is designed for reliability in conditions with electrical noise, vibration, and temperature extremes. Applications include process industries such as oil and gas refining, chemical manufacturing, and power generation, where accurate data acquisition is critical for control and safety. The AAI143-H50/A4S00 integrates seamlessly with Yokogawa's engineering tools for configuration and maintenance, exemplifying Yokogawa's commitment to delivering high-performance and reliable automation solutions.
