What is industrial Automation

Industrial Automation is really a technique by which we make hand over human control to machines. In https://idealprocessandautomation.com.au/ are programmed to accomplish the tasks which people used to achieve. Why it is done? Because of its advantages: Through Industrial automation we are able to do mass production with less manpowerQuality from the product is increasedSafety of man & equipment is increasedMore accurate process controlSince human intervention is less so reliability of the system is higherSystems operate is low power supply, more electronic control so equipment life's higherChanges in process logic becomes easier since logics are changed mostly through software

How industrial automation control system Evolved?

Initially automation was achieved through manual control, operators accustomed to control the process at each and every step. Human intervention was there at every step. Drawbacks were inferior output, errors associated with human involvement affected compromised safety, wastage of raw material, and accuracy of human action.

Then came Pneumatic Control: Industrial automation in this era was achieved through invention of pneumatic controllers in early 1920s. Automation was achieved by controlling air to pneumatic valves, which experts claim were actually switched on/off by relays and switches. They were very bulky and changing with the logic was very complex procedure since a lot of rework was needed to accomplish alteration of logic. So time come to complete task changes was very high

Hard wired logic control: contactors, relays (for switching), timers and counters (for timing and counting) were utilised for achieving desired industrial automation. But these systems also resulted into bulky panels. A lot of wiring was involved so time delivered to complete task was higher. Defect investigation & troubleshooting was complex.

Electronic Control using Logic Gates: In early 60s electronics dominated the method, electronic logic gates were chosen for achieving logical operations. they replaced switching devices like relays and contactors in the control circuits. Electronic times & counters replaced mechanical timers & counters. Due to using electronics space and requirements reduced, maintenance requirement reduced & systems were more reliable.
