Description

ABB AI830A analog input module

Channels and Connections: It has 8 channels and uses a 3-wire connection for the resistance temperature detector (RTD), which can ensure measurement accuracy. Moreover, all RTDS must be isolated from ground.
Input type: It can be used in conjunction with Pt100, Cu10, Ni100, Ni120 or resistive sensors to measure temperature.
Resolution: It has a 14-bit resolution and can accurately measure temperature values.
Functional features: The module can linearize the temperature and convert it into Celsius or Fahrenheit, making it convenient for users to directly obtain the required temperature unit. Each channel can be configured independently to meet the requirements of different application scenarios. In addition, the input end can monitor open circuits and short circuits, and is equipped with an input grounding sensor to ensure the reliability and safety of the measurement. Meanwhile, the cycle time of the power supply frequency filter can be set through the MainsFreq parameter, providing 50Hz or 60Hz notch filter to reduce the influence of power supply frequency on the measurement.
Technical parameters: The update cycle time is 150+95× (number of active channels) ms; The common-mode rejection ratio is greater than 120dB at 50Hz and 60Hz (under a 10Ω load). The normal suppression ratio is greater than 60dB at 50Hz and 60Hz. The rated insulation voltage is 50V. The dielectric test voltage is 500V AC. The power consumption is 1.6W. The operating temperature ranges from 0℃ to + 55℃. The storage temperature ranges from -40 ℃ to + 70℃.

Application scenarios:
Chemical industry: It is used to monitor key parameters such as temperature, pressure and liquid level of reaction vessels to ensure production safety and product quality.
In the power industry, it can be used in power plants and substations to monitor the operating status of equipment and power parameters, improve the operational efficiency and stability of the power system, and ensure reliable power supply.
Pharmaceutical industry: Applied in the pharmaceutical production process, it precisely monitors parameters such as temperature, humidity and pressure.
Manufacturing industry: In the painting workshop of automobile manufacturing, monitor the temperature, humidity and pressure of the spray booth to ensure the quality of the spray painting. In electronic manufacturing, monitoring various operating parameters of the surface mount technology (SMT) machine can promptly detect equipment malfunctions, thereby enhancing production efficiency and product qualification rates.
