Functional Features

  • Multi-channel Signal Acquisition: With 8 input channels, it can simultaneously collect multiple analog signals, improving the efficiency of signal acquisition.
  • High Precision and Stability: It has 12 – bit resolution and low error (0.1%), and the temperature drift is small, ensuring the accuracy and stability of signal acquisition.
  • Strong Anti-interference Ability: It has a high common mode rejection ratio and can resist the interference of NMR (50 Hz, 60 Hz). Protective sensors make it suitable for harsh interference environments.
  • Overload Protection: It has a strong overload capacity, which can withstand a certain multiple of overload input for a short time, avoiding damage to the module due to excessive input signals.
  • HART Communication Support: The input can withstand HART communication, facilitating data interaction and communication with other HART – compatible devices.
  • Easy Installation and Maintenance: Process and power connections are made through detachable connectors, which simplifies the installation and maintenance process and reduces the difficulty of on-site operation.

Application Scenarios

  • Industrial Automation Production Lines: It is used to collect analog signals such as temperature, pressure, and flow in the production process, providing data support for the monitoring and control of the production line, ensuring the stable operation of the production line and the quality of products.
  • Power Industry: It can collect analog signals of power system parameters (such as current and voltage), and transmit the data to the control system to help monitor the operation status of the power system and ensure the safe and stable operation of the power system.
  • Petrochemical Industry: In petrochemical production processes, it is used to collect analog signals of various process parameters, such as the concentration of chemical substances and the pressure of pipelines, to ensure the safety and efficiency of the production process.
  • Metallurgical Industry: It is applied to collect analog signals in metallurgical production, such as the temperature of smelting furnaces and the speed of rolling mills, to realize the precise control of the metallurgical process.
  • Water Treatment Industry: It can collect analog signals such as water level, water pressure, and water quality parameters in the water treatment process, providing a basis for the automatic control of the water treatment system.
