Yokogawa AAI835-S00

Working parameters

Input signal range: The input signal range is very wide. Yokogawa AAI835-S00 supports input signals such as 4 - 20 mA DC, 1 - 5 V DC, etc. for analog input. This enables it to communicate with a wide range of sensors commonly used in industrial processes to monitor temperature, pressure, flow or other physical parameters. Input signal measurements are generally in a high-precision range for precise signal acquisition.

Analog output signal: 4 - 20 mA DC or 1 - 5 V DC. This enables it to communicate control signals to actuators or other downstream devices. The output resolution is sufficient to control the connected equipment, ensuring that process control remains effective.

Power supply requirements: During operation, it requires a standard power supply voltage, typically in the voltage range of 24 V DC. The power consumption is designed to be both powerful and reliable, with uniform performance. It performs stably in industrial environments where power supply variations and noise are normal.

Product Features

Performs signal conversion and conditioning: The Yokogawa AAI835-S00 is responsible for performing the important signal conversion and conditioning processes. It converts the raw/untouched library signal received from the sensor into a complete and more accurate variant. This will involve filtering out any noise or interference in the signal, amplifying it if necessary, and linearizing it to provide the appropriate relationship between the input physical quantity and the output signal.

Control and Monitoring: The Yokogawa AAI835-S00 plays an important role in the control loop. It is able to receive setpoints from a central control system or operator interface and compare them to the measured values. It compares the results to this reference and calculates the control output required to manipulate the process. At the same time, it tracks the process variables, providing information about the state of the process. Therefore, it is also able to generate an alarm if the process variable deviates from the normal range, thus alerting the operator to a possible problem.

Communication Interface: The Yokogawa AAI835-S00 has communication interfaces such as the HART (Highway Addressable Remote Transducer) protocol. This enables communication with other industrial network devices. It allows the exchange of data related to process variables, control settings, and diagnostic information. This also allows for easy integration into a wider DCS or other industrial automation architecture.

Applications

Petrochemical Industry: The Yokogawa AAI835-S00 is used to measure and control a wide range of process parameters in refineries and petrochemical plants. Pipeline-based: For example, it is used to monitor and control crude oil flow, pipeline pressure, or reactor temperature. It allows for safe and efficient flow of a large number of processes occurring in petrochemical production.

Power Generation: It is used in power plants to measure and control parameters such as steam flow, boiler temperature, generator output voltage and current. It is essential for the stability and efficiency of the power generation process to maintain reliable power generation.

Pharmaceutical and Food Processing: The pharmaceutical and food processing industries, where precision and quality control are critical, use the Yokogawa AAI835-S00 to measure and control specific parameters such as temperature, pressure, and flow in the manufacturing process. For example, in a pharmaceutical production line, it is responsible for accurately dosing and mixing ingredients by precisely controlling the flow of liquids.
