Description

• Physical and Environmental Parameters
  • It has a compact structure with dimensions of 170mm × 105mm × 32mm and a weight of approximately 120 grams, allowing for easy installation in standard control cabinets and saving installation space.
  • The operating temperature range is -20°C to +50°C, and the storage temperature range is -40°C to +70°C, which can adapt to the temperature changes of general industrial sites.
  • It can operate stably in an environment with a relative humidity of 5% – 95% without condensation, and its circuit design has good moisture resistance to adapt to the humid working environments in some factories.

Function Features

• Dual Signal Processing and Conversion

  The module can handle both analog and digital signals simultaneously. It receives analog signals such as voltage and current from temperature sensors and pressure sensors, and digital signals such as on/off status from mechanical switches. It converts irregular analog signals into standardized digital signals that can be recognized by the main control system, and also converts digital control commands into analog signals that can drive executive components, realizing bidirectional and efficient signal conversion.

• Wide Protocol Compatibility and Smooth Data Exchange

  By supporting Modbus, Profibus and other mainstream industrial communication protocols, the module breaks the compatibility barriers between different brands of industrial equipment. With the RS485 communication interface, it can establish stable communication links with PLCs, touch screens, and other control devices in the system, realizing real-time data sharing and ensuring the coordinated operation of the entire industrial control system.

• Efficient Energy Utilization and Stable Power Supply

  With an energy conversion efficiency of over 90%, the module reduces unnecessary energy consumption during long-term operation, which is in line with the energy-saving needs of modern industrial production. Its stable 5VDC output and maximum 10A output current can provide continuous and reliable power support for low-power industrial equipment such as small relays and micro-sensors, avoiding equipment malfunctions caused by unstable power supply.

• Fault Monitoring and Early Warning

  The module is integrated with fault detection and monitoring capabilities. It continuously monitors the status of signal transmission and its own circuit operation during work. When it detects anomalies such as signal interruption, connection failure, or abnormal voltage, it can immediately trigger an alarm signal and send fault information to the upper – level control platform. This allows maintenance personnel to quickly locate and handle faults, reducing downtime.

Application Scenarios

• Power Plant Turbine Control

  In thermal power plants and gas-fired power plants, this module is integrated into the control system of turbines and generators. It processes analog signals such as the exhaust temperature of turbines and the output current of generators, and transmits control signals to the servo valves and regulating valves of turbines. It helps the control system accurately adjust the operating parameters of the equipment, ensuring stable power generation and safe operation of the power generation equipment.

• Petrochemical Process Control

  In petrochemical production processes such as oil refining and chemical synthesis, the module is used to monitor and control reaction kettles, pipelines, and other key equipment. It receives pressure and temperature signals from sensors installed on the pipelines and reaction kettles, converts and processes these signals, and then sends control commands to the flow control valves and heating devices. It maintains the stability of the chemical reaction environment and prevents safety accidents caused by parameter deviations.

• Automated Production Line Control in Manufacturing

  In automobile manufacturing, electronic component assembly and other automated production lines, this module connects with various detection sensors and mechanical arms. It receives position signals from mechanical arms and quality inspection signals from product sensors, and sends action commands to the executive components of the production line. It realizes precise control of processes such as workpiece transfer and assembly, improving production efficiency and product qualification rates.

• Robot Motion Control in Intelligent Factories

  The module is applied to the control system of industrial robots. It processes position, speed, and torque signals during robot operation, and transmits precise control signals to the robot’s servo motor. It ensures that the robot can complete actions such as grabbing, moving, and placing workpieces accurately, meeting the high-precision operation requirements of intelligent manufacturing processes such as precision component assembly.

• Auxiliary Control of Transformers in Power Distribution Systems

  In urban and industrial power distribution systems, this module is installed in the transformer monitoring and control system. It collects analog signals such as the load current and operating temperature of the transformer, and sends switching control signals to the protective relays of the transformer. When the transformer is overloaded or overheated, it cooperates with the relay to trigger protective actions, ensuring the safe and stable operation of the power distribution network.
