JG-19B transparent hydraulic PLC control training device

The transparent hydraulic PLC control training device is based on our company's syllabus for mechatronics control of gas, electricity and fluid control, and based on our company's YY-18 transparent hydraulic transmission demonstration system, it integrates hydraulic PLC control experimental equipment. Advantages, it adopts an open comprehensive experimental bench structure, which is widely consulted by experts and professors and teachers, and is developed through continuous innovation and improvement. It is an ideal comprehensive experimental equipment in which hydraulic drive control technology and PLC programmable controller control technology are integrated. During the experiment, students can intuitively and perceptively compare and understand the characteristics, features, advantages and disadvantages of electricity and fluid. The hydraulic experimental elements are made of transparent organic materials, which is transparent and intuitive. It is easy to understand the structure, performance and application of dozens of commonly used hydraulic components. Master the working process and principles of dozens of basic experimental circuits. During the experiment, assembling the experimental circuit is fast and convenient. At the same time, it is equipped with an independent relay control unit for electrical control, which is simple and practical. By comparing with PLC, you can deepen your understanding and mastery of PLC programmable controllers.
