What is industrial Automation

Industrial Automation can be a technique where we make give over human control to machines. In industrial automation machines are designed to accomplish the tasks which individuals accustomed 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 strategy is increasedSafety of person & products are increasedMore accurate process controlSince human intervention is less so reliability from the system is higherSystems operate is low energy, 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 accustomed to control the process each and every step. Human intervention was there each and every step. https://idealprocessandautomation.com.au/ were inferior 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 during the early 1920s. Automation was achieved by controlling air to pneumatic valves, which were actually switched on/off by relays and switches. They were very bulky and changing in the logic was very complex procedure since plenty of rework was forced to accomplish change in logic. So time taken up 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 taken 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 usage of electronics space and energy requirements reduced, maintenance requirement reduced & systems were more reliable.
