What is Industrial Automation & How it Evolved

What is industrial Automation

Industrial Automation is a technique in which we make give human control to machines. In industrial automation machines are designed to accomplish the tasks which individuals utilized to achieve. Why it is done? Because of find more info :

Through Industrial automation we could do mass production with less manpower
Quality of the technique is increased
Safety of person & devices are increased
More accurate process control
Since human intervention is less so reliability from the system is higher
Systems operate is low power, more electronic control so equipment our life is higher
Changes 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 employed to control the method at each and every step. Human intervention was there each and every step. Drawbacks were low quality 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 noisy . 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 necessary to accomplish alternation 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 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 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 utilization of electronics space and energy requirements reduced, maintenance requirement reduced & systems were more reliable.
