What is industrial Automation

Industrial Automation is often a technique where we make pay human control to machines. In industrial automation machines are programmed to accomplish the tasks which individuals used to achieve. Why it is done? Because of its advantages:

Through Industrial automation we're able to do mass production with less manpower
Quality with the strategy is increased
Safety of man & tools are increased
More accurate process control
Since human intervention is less so reliability of the system is higher
Systems operate is low power source, more electronic control so equipment life's higher
Changes in process logic becomes easier since logics are changed mostly through software

How industrial automation control system Evolved?

Initially https://idealprocessandautomation.com.au/ was achieved through manual control, operators utilized to control the method at every step. Human intervention was there at each step. Drawbacks were poor output, errors linked to 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 in turn were actually switched on/off by relays and switches. They were very bulky and changing in the logic was very complex procedure since a great deal of rework was forced to accomplish alternation in 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 these systems also resulted into bulky panels. A lot of wiring was involved so time come to complete task was higher. Defect investigation & troubleshooting was complex.

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