Some application cases of B&R 7AO352.70 in the field of industrial automation: Temperature Control System: In chemical production, the temperature control of the reaction kettle is of vital importance. The B&R 7AO352.70 analog output module can convert digital signals into analog signals according to the signals collected by the temperature sensor, and precisely control the power of the heating or cooling equipment. For example, when the temperature is lower than the set value, the module outputs the corresponding analog signal to the heating equipment, making it increase the power to raise the temperature; conversely, when the temperature is higher than the set value, it controls the cooling equipment to start or increase the cooling intensity, ensuring that the temperature inside the reaction kettle is stably maintained within the range required by the process, and guaranteeing the smooth progress of the chemical reaction and the stability of the product quality.
Flow Control System: In the water supply system of a water treatment plant, it is necessary to precisely control the water flow according to the water usage requirements of users. The B&R 7AO352.70 can be used in conjunction with a flow sensor and an electric control valve. The sensor converts the flow signal into an electrical signal and inputs it into the control system. The control system outputs an analog signal through this module to adjust the opening degree of the electric control valve, thereby precisely controlling the water flow, achieving constant pressure water supply, meeting the water usage needs of different users at different times, and at the same time avoiding the problems of water resource waste and unstable water supply pressure.
Motor Speed Control System: On the automated production line, the speed control of the motor has an important impact on the production quality and efficiency of products. For example, in a printing production line, the B&R 7AO352.70 can convert the digital control signal into an analog voltage or current signal according to the requirements of the printing process, and output it to the frequency converter. Through the frequency converter, it can precisely adjust the rotational speed of the motor, making the rotational speed of the printing roller match the printing speed, ensuring the clarity of the printed pattern and the registration accuracy, and improving the quality and production efficiency of the printed products.
