Product Overview

The YOKOGAWA AAI543-H00 is a high-density Analog Output Module designed for the YOKOGAWA CENTUM VP distributed control system (DCS). It offers 16 isolated output channels, ensuring superior noise immunity and eliminating ground loop issues. This module's core function is to convert digital control signals from the Field Control Station (FCS) into precise analog current outputs (4–20 mA). The -H00 suffix denotes that this unit is equipped with HART protocol support, enabling advanced field device communication, configuration, and diagnostics. With its isolation and HART capability, the AAI543-H00 is ideal for safety-critical and performance-sensitive industrial control applications.

Key Technical Specifications

Key Features and Benefits

16 Isolated Output Channels

The 16 isolated channels ensure that each output is electrically separated from others, which prevents interference from noise and ground potential differences. This is particularly important for high-accuracy, mission-critical applications where signal integrity is paramount.

HART Protocol Integration

The HART protocol support (indicated by the -H00 suffix) allows for simultaneous digital communication over the existing analog wiring, enabling remote configuration, diagnostics, and calibration of connected field devices without the need for additional wiring.

High Accuracy and Performance

The module offers an excellent accuracy of ±48μA (±0.12% of full scale), ensuring precise and reliable analog current output. With a 10 ms data update period, it provides fast response times, making it suitable for dynamic control systems requiring real-time adjustments.

Wide Load Resistance Range

The AAI543-H00 can drive up to 750Ω load resistance per channel, offering high flexibility in interfacing with a variety of field devices. This load capacity ensures compatibility with a wide range of industrial applications.

Robust Design for Industrial Environments

The module can withstand up to 1500 V AC between output and system, providing robust protection against electrical surges and faults, which is essential in demanding industrial environments.
