II. Technical Parameters

(I) General Parameters

• Power Parameters: The module adopts 24V DC power supply, demonstrating good stability and reliability. In practical industrial applications, it has a certain tolerance to power fluctuations and can work normally within a certain range of voltage fluctuations, effectively ensuring the stable operation of the module in complex industrial power grid environments. In terms of power consumption, the NFAI841-S00 module has low power consumption, approximately 2.5W. The low-power characteristic not only reduces energy consumption costs but also reduces the heat generation of the module itself, prolonging its service life and reducing maintenance frequency.

• Environmental Parameters: The operating temperature range is set between -20°C and 60°C. The module can operate stably whether in outdoor equipment in cold regions or in industrial workshops with high-temperature environments. The relative humidity adaptation range is 10%-90% (non-condensing), which means it will not malfunction due to humidity issues in humid production environments such as food processing workshops and sewage treatment plants. In terms of storage, its storage temperature range is -40°C to 80°C, providing reliable protection for the module during transportation and long-term idle storage. Even in extreme temperature environments, the performance of the module can be ensured not to be affected.

• Physical Parameters: The module has a compact size of 110mm×35mm×100mm (length × width × height). This small structure makes it extremely convenient to install in environments with limited space such as control cabinets, which can effectively save valuable installation space and facilitate integration with other equipment. With a weight of approximately 300g, its lightweight feature allows operators to handle it easily during installation, disassembly and maintenance, reducing labor intensity and improving work efficiency.

(II) Special Parameters

• Input Channels: The NFAI841-S00 module is equipped with 8 analog input channels. This rich configuration enables it to connect multiple channels of different types of analog signals simultaneously. In complex industrial production lines, it can collect signals of various key parameters such as temperature, pressure and flow at the same time, meeting the needs of simultaneous monitoring and control of multiple parameters and providing sufficient data sources for a comprehensive grasp of the operating status of the production process.

• Input Signal Types: It supports a variety of common input signal types. The input voltage range includes ±10V, which is suitable for some sensors sensitive to voltage signals, such as certain high-precision pressure sensors. The input current range is ±20mA, which can be perfectly adapted to many industry-standard current-type sensors, such as common temperature transmitters. The support for diverse signal types enables it to flexibly cope with various complex industrial monitoring scenarios, whether it is the monitoring of high-precision experimental equipment or the operation monitoring of large industrial production equipment.

• Output Channels: It also has 8 analog output channels, which can accurately output processed signals to drive various actuators. In chemical production, according to the instructions of the control system, the opening of control valves can be adjusted through the output channels to precisely control the flow of materials. In manufacturing, it can drive frequency converters to adjust the speed of motors, achieving precise control over the operating speed of production equipment and ensuring the accuracy and stability of the production process.

• Signal Processing Accuracy: In the signal conversion process, 16-bit A/D conversion technology is adopted. This high-precision conversion technology can accurately convert analog signals into digital signals with extremely high conversion accuracy, ensuring the accuracy and reliability of collected data. In the process of collecting temperature signals, it can be accurate to tiny temperature changes, providing a solid data foundation for the precise control of the production process. At the same time, the module also has a high precision control capability for output signals, ensuring the stability and accuracy of output signals and meeting the requirements for precise control of actuators in industrial production.
