What is industrial Automation

Industrial Automation is a technique where we make give human control to machines. In industrial automation machines are designed to accomplish the tasks which human beings used to achieve. Why https://click4r.com/posts/g/12328399/ is done? Because of its advantages: Through Industrial automation we are able to do mass production with less manpowerQuality of the technique is increasedSafety of individual & devices are increasedMore accurate process controlSince human intervention is less so reliability from the system is higherSystems operate is low power supply, more electronic control so equipment every day 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 method at each step. Human intervention was there at every 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 plenty of rework was forced to accomplish alternation in 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 chosen for achieving desired industrial automation. But these systems also resulted into bulky panels. A lot of wiring was involved so time taken up 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 used 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 use of electronics space and energy requirements reduced, maintenance requirement reduced & systems were more reliable.
