What are the Main Components of an Automation Electronics System?

Automation is the use of machinery, control systems, and information technology to increase productivity in production processes while reducing the need for considerable human involvement. In industrial settings, automation is critical for improving plant operations by installing various control systems such as Programmable Logic Circuits (PLCs), Human-machine Interfaces (HMIs), and robots.


Automation, which incorporates logic and programming, delivers precise instructions to machines for specific functions, considerably improving industrial performance. Modern industrial automation systems rely on critical electronic components capable of replicating human functions. Selfguard Automation and Controls the leading manufacturer of automatic changeover switch is here to assist you. This article goes over the essential components of automation electronics systems, such as sensors, network connections, controllers, and actuators, as well as some upcoming technologies in the field of industrial automation.


Sensors are Essential Components in Industrial Automation


Automation electronic systems, like our senses, use technology such as cameras, pressure gauges, temperature sensors, photoelectric detectors, microphones, accelerometers, and flow meters to collect information needed to complete a job or achieve goals.


These sensors are critical in industrial processes because they convert physical data into electrical signals while accurately measuring vital parameters such as position, speed, acceleration, humidity, heat flow, pressure, temperature, and so on.


The information gathered by these sensors is critical for monitoring and regulating manufacturing processes, maintaining quality, preventing accidents, and delivering real-time information to human management.


According to a paper published in the journal Sensors International, sensors for automation systems have evolved significantly in terms of sophistication, compactness, and dependability in severe environments. Further downsizing, electrical noise minimization, and sensor cost reduction are all active development areas for automation sensors.


Controller: The Central Hub of the Industrial Automation System


Much like our brains, which are the most complex electrical signal processors we know of, an automation system's controller integrates sensor inputs to make informed decisions about sending signals to actuators and other controllable machine components.


Automation system controllers have evolved from simple mechanical relays to fast computers with abundant digital storage capacity, allowing the execution of complex algorithms such as machine learning and other types of artificial intelligence. Programmable Logic Controllers (PLCs) are the most widely used controllers in the industry today.


Factory Controls, with over 30 years of industry experience, offers a diverse choice of PLC controllers sourced from major automation system manufacturers worldwide. The goal is to offer solutions that empower industrial clients by giving them complete control over their plant operations.


Actuators: The Muscle of Automation Systems


We use our bones and muscles to lift, move, swing, and pull heavy objects to produce marketable goods. This task is accomplished using industrial automation, which combines actuators, valves, engines, and pumps. Compared to artificial intelligence, these are not new concepts, and most of the technology, such as hydraulics and electrical motors, has been around for a long time.


Nonetheless, advances in battery packs and permanent-magnetic brushless electrical motors have made them smaller (and hence more energy-dense) and more efficient, expanding the use of diverse actuators and opening up new options for automation.


Emerging Technologies for Industrial Automation Systems


Companies use new technologies to address common workflow challenges. The industrial automation industry is constantly changing as a result of the advancement and application of digital technology.


By 2028, the industrial automation industry is expected to be worth about $295 billion. The rise of data-driven operations in firms has increased the demand for innovative technologies.


Programmable logic controllers have changed throughout time. They provide a low-cost and accurate solution for process control. Soft PLCs are automation systems that use software to control activities. Software solutions improve the performance, adaptability, and flexibility of PLCs. Soft PLCs have the potential to revolutionise industrial technology. From 2023 to 2028, the PLC market is expected to increase at a compound annual rate of 4.23%.
