产品介绍
The Yokogawa AMM22 Multiplexer Module is a high-performance I/O module designed for integration within Yokogawa’s CENTUM and ProSafe-RS control systems. It functions as a signal multiplexer, enabling the connection / multiple analog inputs or temperature sensors—such as RTDs and thermocouples—to a single controller input, effectively expanding input capability while reducing the number / channels required.
Engineered for reliability and efficiency, the AMM22 /fers seamless data acquisition and conversion with high signal accuracy. It is typically used in industrial automation environments where monitoring a large number / sensor signals with reduced wiring and enhanced flexibility is essential.
The AMM22 is DIN rail mountable and includes built-in diagnostics and channel scanning capabilities. This module is a critical component in process industries such as oil & gas, petrochemical, power generation, and water treatment, ensuring precise process control and continuous plant monitoring.
