Our business purpose is to develop high technology, insist on comprehensive innovation, and benefit human society. We will never relax our vigilance. Our company attaches great importance to enterprise values from top to bottom, and is strict with the construction of enterprise culture.
Mini PLC Controller Basic Structure
A PLC is essentially a computer specially designed for industrial control. Its hardware structure is basically the same as that of a microcomputer. It basically consists of power supply, central processing unit, memory, input unit and output unit.
1. Power supply: used to convert alternating current into direct current required by PLC. At present, most PLCs are powered by switching regulated power supplies.
2. Central Processing Unit (CPU): The CPU is the control center and the core part of the PLC. Its performance determines the performance of the PLC.
3. Memory: It is a semiconductor circuit with memory function, which is used to store system programs, user programs, logic variables and other information.
4. Input unit: It is the input interface between the PLC and the controlled device, and it is the bridge for the signal to enter the PLC. Its function is to receive signals from the main command element and the detection element.
5. Output unit: It is also the connection between the PLC and the controlled device. Its function is to send the output signal of the PLC to the controlled device, that is, the CPU converts the weak signal into a level signal, and then drives and executes the controlled device.
Apply generalization
1. Open loop control
The open-loop control of the switch is the most basic control function of PLC.
2. Analog closed loop
For the analog closed-loop control system, in addition to the digital input and output, there are also analog input and output points.
3. Digital control
When the control system has rotary encoder and pulse servo device, PLC can realize the function of receiving and outputting high-speed pulse, and realize digital control.
4. Data collection and monitoring
Since PLC is mainly used for field control, collecting field data is a very necessary function. On this basis, PLC is connected with the host computer or touch screen, which can not only observe the current value of these data, but also conduct statistical analysis in time.
Tecoo, as a professional electronic manufacturing service provider, provides OEM and customization services for mini PLC controllers.
Since the establishment of the company, through continuous technological innovation, the product manufacturing process has been improved day by day, the production scale has been continuously improved, and it has developed into a large-scale Cotrust PLC Cth200 H224X 14di/10do Transistor Output Ethernet Port CPU Support Analog and Can Expansion Boards production enterprise in China. We believe that enterprises need to consciously fulfill their social responsibilities while pursuing value maximization, and create material and spiritual wealth for society as much as possible. It is not the enterprise that decides the market, but the market that decides the success or failure of the enterprise. The market is the starting point and the destination point of all the work of the enterprise.
