Product Description
Product Overview
- The Yokogawa AAI143-H53/K4A00 Analog Input Module is a robust component designed for Yokogawa’s industrial control systems, such as CENTUM VP or ProSafe-RS, to process 4 to 20 mA signals from field devices like transmitters. Featuring 16 isolated input channels with HART communication, this module supports dual-redundant configurations for enhanced reliability. With a rated accuracy of ±16 µA, a 40 ms data update frequency, and a transmitter power supply ranging from 16.15 V to 26.4 V, it is optimized for precise analog input handling. Equipped with a KS Cable Interface Adapter for connecting to an AEA4D Terminal Board, it weighs approximately 0.34 kg (or 0.39 kg with a signal cable interface adapter) and includes ISA Standard G3 compliance for operation in temperatures from -20 to 70°C, making it ideal for industrial automation applications.
