pressure process control trainer

1) Composition and structure characteristics 1. Simple structure: the overall structure has a skeleton and an executive part of the control cabinet, 2. Convenient operation, all operation, display and execution components are installed with external leakage, which is convenient for observation and operation 3. The overall frame is made of stainless steel to prevent the equipment from rusting 4. Only single-phase three-wire AC power supply can be put into use, and the floor space is small, saving housing and reducing infrastructure investment 5. The structure design of the open experimental object makes the experimental object intuitive and easy to understand. 6. The design of the hardware object fully considers the certainty of its mathematical model, which is consistent with theoretical textbooks. 7. The parameters and characteristics of the selected instruments meet the design requirements of the system, and the experimental results are ideal. 8. The disassembly and assembly of instruments and meters deepens students' understanding of engineering instruments and meters, especially the internal principles of devices. 9. A variety of control signals, a variety of control signals and control methods can be selected according to the experimental project 10. You can do DIY experiments; the training device can change the experimental objects and connection methods according to user requirements 11. Human-computer interactive experiment. The configuration software is used for interactive operation, that is, what you see is what you get, and data can also be collected. 2) Security protection 1. The power supply has protections such as leakage, overvoltage, overcurrent, and short circuit, which protect the safety of trainers. 2. Separation of water and electricity; that is, the control system and the execution system are separated, and all the wiring of the execution system is treated with waterproof measures 3) Configure teaching software
