Digital control systems are used in industries to control and monitor variables such as temperature, humidity, and pressure. The control panels help companies to reduce costs by reducing applicable outputs and controlling predictive behaviors. Using these control panels is a big sings for branding as they are mostly used in refrigeration plants, motor control panels, air compressors, circulation pumps, and manufacturing systems.
There are various benefits and limitations of using digital control panels in an industrial setting. The following are the benefits of using digital control panels.
• Increased Reliability
It is easier to specify and to change a digital control panel to the desired function. This is usually noticeable in sequence control and relays specifically where PLC (Programmable logic controllers) are used in place of the analogue relay system. However, a PLC alone is not reliable enough to be used in some systems such as the emergency shutdown systems and when handling dangerous chemicals. Installing digital control panels promotes reliability.
• Advance control techniques
The use of digital control panels promotes the implementation of complex control techniques. They help a company to take advantage of design tools and a host of analysis. These tools provide a systematic approach when operating plant processes given various specifications. These lead to increased efficiency and better quality of the product produced for the customer.
• There is no loss of signal while migrating from Analogue to digital
The physical quantities measured using digital control panels are usually analogue. The control panels usually monitor, operate on, and control outputs and input of the analogue physical quantities. However, there is no loss of accuracy while converting the analogue signals to digital form. This brings increased accuracy and precision while monitoring and controlling physical quantities using the digital control panels.
• All functions can be programmed
The greatest advantage of digital control systems is that you can easily modify and set functions without a struggle. The controller can be programmed to change settings at any time of the day. For example, there might need to reduce the temperature at night or boost water for some hours at a certain time of the day. Digital control panels can be used to achieve this and can also be used to perform the programming an industry needs to keep running effectively and efficiently as possible.
Limitations of Digital control panels
There are only two major disadvantages associated with digital control panels. one is that it requires skills and training to operate digital control panels. Secondly is that Security is shell oriented. Graphical interfaces of digital control panels are usually less secure. The control panels usually depend on the relationship between the hardware and the software and the shell and the studded panel. All these connections assist in controlling but brings about compromised security. The popularity of the digital control panel makes it a target for hackers who are looking forward to stealing.
However, these limitations have been offset by the benefits associated with Digital control panels Now that you are aware of the benefits and limitations associated with digital control systems, I hope that you will be able to make a reasonable decision while buying digital control panels for use in your industry.
