Advantages of Xinjie touch screen and PLC wireless measurement and control network solution

Because the current at the input and output ends of the inverter contains high-frequency components, the leakage current formed by the high-frequency components when the inverter is driven is greater than that when the grid power supply is supplied. Because there are many varieties of circuit breakers, in some cases, even the inverter wires and motors ...

Of course, PLC control is much more reliable than relay control, but if the device does not meet the requirements, it will not work. Therefore, the PLC machine should be installed correctly outside. (1) Pay attention to the environment of the installation The temperature should not be lower than 0°C and above 55°C, for example, not installed by a large stove, and ...

Inverters are mainly divided into two categories according to the frequency conversion method: communication/DC/communication and communication/communication inverters. AC/DC/AC inverter, also known as direct inverter, refers to the operation, the first 50Hz power frequency communication power is converted into pulsating direct current through the rectifier module unit, ...

1. High reliability The PLC adopts a series of anti-interference methods in hardware and software, so that it can be directly installed in the industrial site and operate safely and reliably, anti-magnetic, anti-seismic and dust-proof. 2. Programming is simple and easy to grasp ...

1. Operating temperature. The inverter is a high-power electronic component, which is easily affected by the operating temperature, and the product is generally required to be 0-55 °C, but in order to ensure the safety and reliability of the operation, it should be considered to leave room for use, and it is best to control it below 40 °C. In the control box, the inverter ...

With the continuous development of industrial automation, PLC is widely used in industrial control professions. No matter how strong the PLC product is, it often fails to work normally. All kinds of brands of PLC have the function of self-diagnosis, but the skill of PLC repair is that when the PLC is abnormal, the function should be fully used.

The grounding policy is nothing more than to avoid disturbance for safety, and the policy of grounding to PLC must not be attached to the disturbance at the power supply and input and output terminals, so the accurate grounding system is one of the primary methods for the PLC control system to resist electromagnetic disturbance. There are floating and direct grounding formations.

1. Acknowledging the characteristics of the load such as load type, speed, and nature; 2. Acknowledging whether it is continuous work, long-term work, short-term work and other work characteristics; 3. Acknowledging the maximum consumption output value and the extra output value; 4. Acknowledging ...

1. Select the power supply with excellent performance and press the disturbance introduced by the power grid The power supply of the PLC controller is powered by a non-power line, and is powered by a special line directly led by the main bus of the low-voltage distribution room. Barrier transformer should be selected, the transformer capacity should be 1.2-1.5 times larger than the actual need, and can be used in the barrier...

A universal inverter is an electronic device used to control the speed of an electric motor, which can change the speed of the motor according to the demand, and then achieve higher output power and power savings. Universal inverters have a wide range of application scales and can be used for various types of electric motors, including communication motors, direct ...

　　1. Four-wire resistive touch screen: It is not afraid of dust, oil and photoelectric disturbance, and is afraid of scratches is its main defect. It is suitable for public places with fixed users, such as industrial control sites, offices, homes, etc.; 2. Five-wire resistor ...

Introduction to Thermal Transfer Transfer printing refers to a printing method that selects the corresponding pressure to transfer the graphics and text on the intermediate carrier film to the substrate, and according to the different selection pressures, transfer printing can be divided into water transfer printing, heat transfer printing, air transfer printing, screen transfer printing, low temperature transfer printing and so on. In the meantime, the heat ...

First, let's talk about PLC first About PLC, don't just see the PLC module, but a variety of PLC modules + host computer channel software to form a well-structured control systemPLC module is composed of microprocessor + memory + firmware + programming to complete the modular function. PLC control system ...
