Modular Electrical Training Equipment with Siemens S7-200 SMART SR40 PLC and Adjustable 0-240V Output

The "Electrical Control and Instrumentation Lighting Circuit Training and Assessment Device" is a training device developed based on the training circuits listed in the primary and intermediate level electrician skills assessment content issued by the Ministry of Labor and Social Security. Through practical operation of this device, students can quickly master the practical application technology and operational skills of this course. This training device is not only suitable for students to conduct skills training, but also an ideal equipment for primary and intermediate level electrician skills assessment in colleges, universities, technical schools, vocational schools, and labor vocational skills appraisal departments.

1. All electrical control circuit components are mounted on the mounting plate, which serves as a hanging plate. This makes operation convenient and replacement easy, and facilitates the expansion of functions or the development of new training programs. The selection of operation content is typical, practical, and scientific.
2. The operating console only requires a three-phase four-wire AC power supply to be put into use;
3. The control circuits and specially designed small motors used for skills training can simulate various electrical drive systems in a factory, meeting the requirements of maintenance electricians for skills training such as installation, debugging, fault analysis, and troubleshooting;
4. In the relay contact control circuit training , all components are led to the terminals through wires. Students only need to connect the wires to the terminals, which helps protect the components; during training, wiring is done through cable trays for process wiring training;
5. Contactors and thermal relays and other electrical components are all from well-known domestic and international brands, ensuring the quality and performance of the equipment;
6. It is equipped with voltage-type and current-type leakage current protectors to ensure operator safety; each power output has monitoring and short-circuit protection functions. When misoperation or short circuits occur due to wiring errors during training, the device can automatically protect against blown fuses and damage to electrical appliances, ensuring the smooth progress of training;
7. The connection between the training circuit and the device power supply is made through safety sockets and highly reliable sheathed plug-in wires, which is safe and quick;
8. The device is equipped with a three-phase power output short-circuit soft cut-off protection function, which prevents short circuit damage to components due to wiring errors or misoperation during student training. At the same time, it can ensure the smooth progress of training and save training costs.
