Comprehensive training platform for PLC inverter and touch screen

ZN-PBC240 PLC inverter, touch screen comprehensive training platform
1. Overview:
1. Modular design, in the host module, all input and output ports are connected to the experiment board through wires, and each experiment module has independent input and output , Public end. Users can easily expand their own modules.
2. The use of physical products for DC motors, relays and sensors improves the authenticity and practicability of the experiment.
3. Equipped with MCGS industrial control configuration software, which can intuitively perform PLC basic instruction exercises, multiple PLC practical application simulation experiments and physical experiments. All experiments have configuration bar graphs for dynamic tracking, and the image of the experimental objects is realistic and close to industry. The practical application of the scene, through the training of this device, enables students to adapt to the practical operation of the scene very quickly.
4. Here students can understand and master the structure and principle of the inverter, the installation of the inverter and the use of the interface terminals, the communication between the inverter and the PC, the communication between the inverter and the touch screen, the setting of the inverter's own parameters, and the inverter Setting and optimization of motor operating parameters (acceleration, deceleration, speed change, torque control).
When the program debugging is completed, the touch screen can be used alone to control the frequency conversion system. The touch screen provides a graphical man-machine interface, which can change the parameters of the frequency converter and control the operation of the frequency converter.
2. Technical parameters:
1. Input power: three-phase four-wire: ~220V ±10% 50Hz, output power 24V, 2A.
2. Working environment: temperature -10℃~+40℃ relative humidity <85% (25℃) Altitude <4000m
3. Safety protection: This experimental device is equipped with a leakage protection switch, which has the functions of leakage voltage and leakage current automatically cutting off the power supply. Comply with national safety standards.
4. The PLC host adopts Siemens S7-200 series CPU226, input 24 points, output 16 points.
5. The inverter host adopts Siemens MM440 / 0.37KW, 6SE6 440-2UC13-7AA1, and is equipped with a BOP panel.
6. The touch screen adopts Siemens SMART 700 IE, 6AV6 648-0BC11-3AX0 7.
180W three-phase asynchronous motor.
