YPC-08A Hydraulic PLC Control Experiment System Hydraulic PLC Control Training Device System

I. Overview

YPC-08A hydraulic PLC control experiment system is designed according to the requirements of general textbooks such as "Hydraulic Transmission" and with reference to the teachers and students. In addition to the conventional hydraulic basic control circuit experiments, the system can also perform hydraulic control technology application experiments, hydraulic technology course design, and programmable controller (PLC) learning and basic application experiments. Laboratory equipment.
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.


Features

1. YPC-08A hydraulic PLC control experiment system is mainly composed of experimental bench, hydraulic components and electrical and control devices.
2. The experimental components are made of transparent organic materials. Transparent hydraulic components can more clearly show the structure, performance and use of the components.
3. The electrical main control unit is controlled by a PLC programmable controller, which can communicate with the PLC microcomputer to realize the intelligent control of the microcomputer.
4. The independent relay control unit is used for electrical control. Through comparison, the superiority of the PLC programmable controller is highlighted, and the understanding and mastery of PLC programming is deepened.

(220V output is used to control the solenoid valve in our hydraulic products)
(3) PLC programmable controller: Japan's Mitsubishi FX1s-14MR (relay output mode), PLC type can be replaced according to user needs.
(4) Input module: It is connected with PLC by cable 9 pin 232 interface. After the connection is provided, the PLC provides 8 main command input signals (of which 2 are normally closed signals), and provides automatic control signals for the PLC through the signal jack. (Such as: position switch position signal, etc.); output module: 9-pin 232 interface connection with PLC. Control the on-off of the solenoid valve through the output interface jack; relay control module: After connecting with the power module, perform the master signal control, and provide an automatic control signal interface for automatic control. Control the on-off of the solenoid valve through the output port jack.

(5) Hydraulic pumping station (with digital tachometer):
Working power: AC: 220V 50Hz
