What is industrial Automation

Industrial Automation can be a technique in which we make hand over human control to machines. In industrial automation machines are designed to accomplish the tasks which people employed to achieve. Why it is done? Because of its advantages: Through Industrial automation we are able to do mass production with less manpowerQuality in the product is increasedSafety of person & devices are increasedMore accurate process controlSince human intervention is less so reliability from the system is higherSystems operate is low power source, more electronic control so equipment life is 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 utilized to control the task each and every step. Human intervention was there each and every step. Drawbacks were poor output, errors involved with human involvement affected compromised safety, wastage of raw material, and accuracy of human action.

Then came Pneumatic Control: Industrial automation within this era was achieved through invention of pneumatic controllers at the begining of 1920s. Automation was achieved by controlling air to pneumatic valves, which in turn were actually switched on/off by relays and switches. They were very bulky and changing with the logic was very complex procedure since a great deal of rework was needed to accomplish alteration of logic. So time delivered 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 https://idealprocessandautomation.com.au/ 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 procedure, electronic logic gates were utilized 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 utilization of electronics space and requirements reduced, maintenance requirement reduced & systems were more reliable.
