Yokogawa Electric Corporation AAI143-H53 S1 Analog Input Module

The Yokogawa AAI143-H53 S1 Analog Input Module provides 16 isolated analog input channels for CENTUM DCS cabinets, control panels, and industrial automation systems, expanding input capacity and ensuring reliable signal acquisition from field transmitters in industrial control systems. It accepts 4–20 mA signals as standard and, depending on model, 1–5 VDC inputs, with a data update rate of approximately 10 ms and an accuracy of about ±16 μA, enabling accurate measurement of process variables such as pressure, temperature, flow, and level. The module supports HART communication for advanced diagnostics and integrates with Yokogawa CENTUM VP, FIO systems, and other Yokogawa automation platforms, with a transmitter power supply of roughly 19–25.5 VDC (2-wire) and channel-to-system isolation. Common replacements include Yokogawa AAI143-H03 and AAI141-S00 Analog Input Modules, and the AAB841 Analog I/O Module is listed as a related option for expansion in oil & gas, chemical plants, power generation, and manufacturing environments.
