• Output Channels and Signal Types: Equipped with 4 independent analog output channels, each channel can output standard analog signals, including 4 - 20mA DC current signals and 0 - 10V DC voltage signals. These standard signals are widely used in the industrial field and can be perfectly compatible with various actuators such as control valves, frequency converters, and servo drives, meeting the control signal requirements of different equipment.

• Output Accuracy and Resolution: It has extremely high output accuracy, with an error usually not exceeding ±0.1% of the full scale, ensuring that the output analog signal can accurately reflect the instructions of the control system. The resolution reaches 16 bits, which means the module can finely adjust the output signal, realizing precise control of the actuator and improving the control accuracy of the industrial production process.

• Power Supply Specifications: Powered by a 24V DC power supply, it matches the common power supply standards in industrial automation systems and has strong versatility. The power consumption is low. Under normal working conditions, the power consumption per channel is about 0.5W, and the total power consumption of the entire module does not exceed 3W, which helps reduce the overall energy consumption of the system and conforms to the industrial development trend of energy conservation and environmental protection. At the same time, the module is equipped with an overvoltage protection function. When the power supply voltage fluctuates abnormally, it can effectively protect the internal circuit of the module from damage, improving the safety and reliability of the module.

• Environmental Adaptability: The operating temperature range is -25℃ to +70℃, which can adapt to extreme temperature environments that may occur in industrial sites, whether it is a high-temperature metallurgical workshop or a low-temperature storage area, it can maintain stable working performance. The relative humidity is 5% - 95% (non-condensing), allowing normal operation in humid environments without being affected by humidity changes. In addition, the module also has strong anti-electromagnetic interference ability, meets relevant industrial standards, and can stably output analog signals in industrial sites with strong electromagnetic interference, such as near high-power motors and transformers.

• Physical Specifications: Adopting a compact modular structure design, the size is approximately 100mm×80mm×60mm, and the weight is about 0.4kg. It occupies a small space, which is convenient for installation and layout in the control cabinet, especially suitable for industrial environments with limited space. The installation method is standard DIN rail mounting, and the installation process is simple and fast, which can be quickly integrated into the existing DCS system, reducing installation and commissioning time.

• High-Precision Signal Conversion and Output: The module uses advanced digital-to-analog conversion chips and precision signal conditioning circuits inside, which can accurately convert digital control commands sent by the control system into analog output signals. Its high-precision conversion performance ensures the accuracy and stability of the output signal. Even during long-term operation, it can maintain low drift, ensuring that the actuator can act accurately according to the requirements of the control system, improving the control accuracy of the industrial production process and the consistency of product quality.

• Channel Independence and Isolation: The 4 output channels adopt an electrical isolation design, with an isolation voltage of 2500V AC, which effectively avoids signal interference between channels and ensures the independence and stability of the output signal of each channel. At the same time, isolation is also carried out between the module and external equipment to prevent external voltage or current fluctuations from affecting the internal circuit of the module, improving the anti-interference ability and working reliability of the module in complex industrial environments.

• Fault Diagnosis and Alarm: It has a complete self-diagnostic function, which can real-time monitor the working status of the module, including power supply status, digital-to-analog conversion circuit status, output channel load status, etc. When an abnormal situation is detected, such as the output signal exceeding the normal range, channel short circuit, power failure, etc., it will immediately send fault alarm information to the upper-level control system through the internal communication bus, and display the fault location and type through the status indicator light on the module, facilitating maintenance personnel to quickly locate the cause of the fault, shortening the fault troubleshooting and repair time, and improving the availability of the system.

• Flexible Configuration and Calibration: It supports parameter configuration and calibration through dedicated configuration software. Users can flexibly set parameters such as the signal type, range, and alarm threshold of each output channel according to actual application needs. The calibration process is simple and convenient, without the need for professional calibration equipment. Zero and full-scale calibration can be completed through software, ensuring that the module always maintains high-precision output performance during long-term use.

• Process Control Industry: In process control fields such as chemical industry, petroleum, natural gas, and pharmaceuticals, the DSAO110 57120001-AT module is widely used for precise control of various process parameters. For example, in chemical production, the module outputs a 4 - 20mA current signal to control the opening of the control valve, thereby accurately adjusting key parameters such as material flow, pressure, and temperature in the reaction kettle, ensuring that the chemical reaction proceeds according to the preset process curve, improving product quality and production efficiency, while ensuring the safety and stability of the production process.

• Metallurgy and Building Materials Industry: In the production processes of iron and steel, non-ferrous metal smelting, as well as building materials such as cement and glass, it is necessary to precisely control furnace temperature, material ratio, equipment speed, etc. The module can output corresponding analog signals to control the gas flow of the burner, the conveying speed of the feeder, the speed of the fan, etc., realizing precise regulation of the production process, reducing energy consumption, reducing environmental pollution, and improving product output and quality.

• Power Industry: In power production facilities such as thermal power plants and hydropower stations, the DSAO110 57120001-AT module is used to control the speed regulation system of steam turbines, the water supply system of boilers, the air volume of induced draft fans and forced draft fans, etc. By outputting precise analog signals, it adjusts the actions of relevant actuators, ensuring the stable operation of generator sets, maintaining the stability of grid voltage and frequency, and improving the reliability and economy of power production.
