Control panels find their use in almost every industry from construction to large scale manufacturing lines and from aeroplanes and lifeboats to food processing plants. Just name an industry and you will be surprised to know how easy it has become to monitor and control everything in a process with these control panels.
The application of control panels in the food industry has grown since last few years and now the manufacturing plants are considered incomplete without them. Here is a brief overview of incidences where you always see a control panel working wonders for you.
- Pet food extrusion line by pet food manufacturer
- Plant control panels for manufacturing concerns. These have PLC rack that is linked by fibre optic cable to the plant-wide DCS system, with battery backed UPS system and Pilz safety relays.
- Chick hatchery plants. Here control panel work with invertors to control conveyors.
- Grinder machine control panel with complex Pilz safety relay interlock system
- Food process skid which also has an evaporator to evaporate as much as 100 tons of evaporated steam per hour. Such a complex system can never run without a PLC control panel.
- Panels for controlling the conveyors to take in the raw material and take out the cooked items from an oven. Bakeries have such systems usually made up of stainless steel.
Electrical Control Panels for process control
Process control is a terminology often used in relation to control panels. It is about maintaining the output of a specific process within a particular range. Process control is extensively used in food industry to maintain consistency and achieve the best and consistent results.
Electrical Control panels are used to maintain values within a specific range; for example, an adjustable valve is often used to retain level in a tank. In this case, a logical statement matches the same pressure at depth set point to the pressure reading of a sensor just lower than the usual level of the liquid. This mechanism helps in determining the value of valve opening for sustaining the level. Here, a PLC output comes into play and calculates an incremental value of the change in the valve position.
PLC control panels are widely used in batch manufacturing where specific quantities of various materials are combines for specific durations to produce an intermediate or end product. Such structures are often seen in the production of food, beverages and medicine. Generally, batch manufacturing is used to produce low to intermediate quantities of products.
Future of control technology
It is the performance or output of the overall system that matters; not the performance of individual components. So, it is important for a system to carry out tasks while maintaining consistency and smoothness. The processors on a system have to outperform. Due to all these reasons, there seems to be a great chance that a PLC will no longer be used in its familiar form.
PLC control panels are amazing as compared to windows based systems. PLC control panels operate in real time, are secure and have high protection against unauthorized access from outside. Moreover, PLCs are believed to be helpful in maintaining systems in long run and supportive in the execution of various tasks. Such supple capability is very significant because standards like IEC61499, that is about functional units of industrial control systems and guideline for distributed intelligence in control systems, are becoming more important than they were in past. While there is a fair chance that both; PLC control systems as well as windows based systems, will prevail in the long run, the PLC takes on the responsibility for all sequences which must be protected, especially in a combination of intelligent systems.
