Yokogawa AAI543-S03/A4S00

Working Parameters

Supported Analog Input Signal Types: It can work with many types of analog input signals. It can directly read 4 - 20mA DC signals commonly used in industrial sensors for measuring parameters such as pressure, temperature and flow. As mentioned above, it is precisely optimized for input impedance to ensure that the signal is received correctly and avoid distortion.

Accuracy: Typically, the accuracy of Yokogawa AAI543-S03/A4S00 is ±0.05% of the range. This accuracy enables reliable control and measurement of important manufacturing applications, where even small deviations can produce significantly poor results. It ensures that the values obtained and used for control operations are highly reliable.

Response Time: Very fast, typically only a few milliseconds. It can also respond quickly to changes in input signals, making it ideal for continuous real-time monitoring and control applications. Therefore, in industrial processes that change rapidly and fluctuate in state, Yokogawa AAI543-S03 can quickly adjust its output in real time to adapt to changes in input signals.

Product Features

Signal Conversion and Conditioning: The Yokogawa AAI543-S03/A4S00 acts as a signal converter, converting the input analog signal into a format suitable for further processing by the control system. It also performs signal conditioning steps such as: amplification, filtering, and linearization. This will improve the signal quality and make it more suitable for precise control and monitoring. Suppose you get some weak and noisy signal from the sensor, in this case, the AAI543-S03 can help amplify and filter that weak signal until you get the correct signal.

Output Capability: The Yokogawa AAI543-S03/A4S00 has a 4 - 20mA DC signal processing output or other configurable output range. This output can be used to drive an actuator or other control device. The processed input signal can be used to control a valve, motor, or other device. Just like in a flow control system, the output of the AAI543-S03 receives feedback from the sensor, opening or closing the control valve based on the feedback to determine the correct flow rate.

Communication and Integration: The Yokogawa AAI543-S03/A4S00 includes communication protocols such as HART (Highway Addressable Remote Transducer). This allows it to be expanded to connect to larger industrial networks. It can interact with different devices such as controllers and field monitoring systems. It allows him to provide diagnostic information, process data, and receive configuration commands through this communication. This allows them to fit seamlessly into contemporary industrial automation architectures.

Applications

Oil and Gas Industry: Yokogawa AAI543-S03/A4S00 is used in refineries and gas processing plants to measure and control different parameters. It can track crude oil flow, pipeline pressure, and reactor temperature. For example, it plays an important role in maintaining the correct temperature and pressure conditions throughout the refining process and is a means to ensure visibility of the final product.

Chemical Industry: Controlling chemical reactions is very important in the manufacture of chemicals. It can monitor the levels of reactants, the flow of chemicals, and the temperature of reaction vessels. It helps ensure that the production of chemicals is safe and efficient.

Power Generation: It can be used to measure and control parameters such as steam flow, boiler water level, and generator output in power plants. It does this through HALPING ONPC (Operational Network for Power Control) to optimally coordinate power generation and plan power planning schedules to ensure smooth plant operation.
