Yokogawa AMM21T Thermocouple Input Multiplexer Module

مقدمة المنتج

The Yokogawa AMM21T is a Thermocouple Input Multiplexer Module meticulously designed for precise multi-channel temperature measurements in industrial environments. Part من Yokogawa’s renowned I/O module series, the AMM21T is engineered for use in high-reliability Distributed Control Systems (DCS), such as the CENTUM VP and CENTUM CS 3000 platforms.

The module enables temperature monitoring from multiple thermocouple types, supporting a wide range من industrial temperature sensors (Type K, J, T, E, B, R, S, N). With high channel density, advanced cold junction compensation (CJC), and channel-to-channel isolation, the AMM21T provides accurate and stable readings—even in electrically noisy environments.

Its compact form factor and robust design make it ideal for use in sectors like power generation, petrochemical processing, and advanced manufacturing, where thermal data acquisition and control are mission-critical.
