With the strong development of science and technology, the operation of machinery and equipment has become much simpler than before. In particular, the PLC control cabinet is an example of this. So what features does the product have, how does it work, and how does it work? Let’s find out with Ben Thanh now.
Thanks to the advent of automation products, the process of operating machines is no longer as labor intensive and manual as before. This is to limit risks to employees and improve work efficiency. Up to now, the operation of machines, equipment, and pumps has been fully automated, with the presence of PLC control cabinets.
What is PLC control cabinet?
This is an electrical cabinet programmed by PLC software, so that it can be automatically controlled for industrial machinery systems according to the requirements of the production process. Operate and monitor by means of operator and touch screen operation.
PLC control cabinet was born to help increase labor productivity, increase accuracy and improve production efficiency significantly. In order to realize production automation, besides mechanical or electrical machines, production lines, etc., it is also necessary to have the presence of controllers and release human labor. PLC control cabinet was born to meet all the above requirements.
The structure of the PLC control cabinet with the main component is the PLC controller. In particular, PLC controllers have many different types from many famous brands such as LS, ABB, Schneider, Mitsubishi, Siemens, etc. Thanks to the function of the controller is to receive and produce signals, it’s an analog signal. Since then, the PLC control cabinet works in a very smart way, which can be controlled by Timer, PID, counting, etc.
From those controllers, the control designer gets the signal through intermediate relays, contactor contacts and thermal relays. From there, control pumps and motors according to the requirements of the electrical system.
Basic Specifications
Size: Depending on the device that needs to be controlled, the cabinet size will be different
• Shell material: Galvanized steel, waterproof stainless steel
• Voltage: 220VAC/ 24VDC
• Controller: PLC brand Schneider, Mitsubishi, LS, Siemmen…
• Expansion modules: DO, DI, AO, AI…
• PLC control source: 24VDC

Function
Thanks to the intelligence from the above controllers, the manufacturer designs and manufactures PLC control cabinets with the following main functions:
– Control switch (On/Off): used in opening and closing pumps, motors, motors…
– Count control (Counter): Used to control the number of counting
– Timer control (Timer): control opening and closing according to time, running in reverse sequence.
– Variable frequency control (PID): high-demand control, frequency converter to serve the water treatment industry, wastewater treatment, motor control, motor …
In addition to the above automatic control function, the PLC control cabinet is also connected to the SCADA remote control and monitoring system to monitor and control pumps and motors. This function is very superior when used in hazardous chemical industries or dangerous areas such as mines …
Advantages
With outstanding advantages such as the installation of the cabinet is quite easy and quick. Along with the programming is not complicated, so the operator can easily use it without having to know about professional expertise when using the PLC cabinet. In addition, the accuracy of the PLC electrical cabinet is very high, you can rest assured during operation and use.
APPLICATION
Currently, control cabinets using PLCs are widely applied in industrial machines, used to control actuators to improve machine productivity, reduce labor and reduce labor force, and improve productivity. High production efficiency.
Normally, PLC control cabinets are installed in control areas of industrial buildings and industrial plants such as: Control conveyors in production lines such as ceramic tiles, building materials, cartons. , dairy, food processing and packaging.
Ben Thanh distributes, consults, designs and constructs all kinds of PLC control cabinets according to the requirements of customers, applying modern technology of big brands such as Mitsubishi, Schneider … to help customers have solutions. effectively achieve maximum performance for the device control system. With a technical team of many years of experience, the control cabinets of KOV VINA are warranted for 1 year or more, maintenance for customers throughout the period of use.
