Application Fields:

• Chemical and Pharmaceutical Field: It can be used in scenarios such as reactor temperature monitoring, pressure control, and liquid level regulation. For example, a pharmaceutical factory uses this module to collect the temperature of fermentation tanks, utilizes its channel isolation design to avoid signal crosstalk, meets the accuracy requirements with 12-bit resolution, reduces the temperature fluctuation from ±2℃ to ±0.5℃, and improves the product qualification rate.
• Energy and Utilities Field: It can be applied to substation voltage/current monitoring, water pump pressure control, wind turbine vibration analysis, etc. Its high sampling rate (500Hz) can capture transient signals and support fault early warning. For example, a coal mine uses this module to collect vibration signals of crushers, combines with AI algorithms to predict equipment life, and reduces annual maintenance costs.
• Manufacturing Field: It can be used for welding current monitoring, coating thickness detection, robot joint temperature control, etc. In equipment such as machine tool manufacturing, textile machinery, and packaging machinery, this module can also accurately collect analog signals to ensure stable operation of equipment and production quality.
• Sewage Treatment Field: Channels can be configured to connect liquid level sensors, etc., for monitoring parameters such as the liquid level of sewage pools. By accurately collecting liquid level analog signals, it provides data support for liquid level control in the sewage treatment process and ensures the normal operation of the sewage treatment process.
• Rail Transit Field: It can be used in scenarios such as rail transit axle temperature detection. By connecting temperature sensors, it can monitor the axle temperature in real time, convert the temperature analog signal into a digital signal for system processing, so as to detect abnormal axle temperature in time and ensure the safe operation of trains.
• Food and Beverage Field: It can be used to monitor parameters such as temperature, pressure, and flow during the production process, such as liquid flow control during beverage filling and temperature control during food baking, to ensure stable product quality and meet production process requirements.
