What is industrial Automation
Industrial Automation is often a technique in which we make pay human control to machines. In industrial automation machines are designed to accomplish the tasks which human beings employed to achieve. Why it is done? Because of its advantages:
Through Industrial automation we could do mass production with less manpower Quality in the strategy is increased Safety of person & products are increased More accurate process control Since human intervention is less so reliability in 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 accustomed to control the method at each and every step. Human intervention was there at each and every step. Everything You Need to Know About Industrial Automation Solutions were substandard quality output, errors linked to human involvement affected compromised safety, wastage of raw material, and accuracy of human action.
Then came Pneumatic Control: Industrial automation with this era was achieved through invention of pneumatic controllers noisy . 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 of the logic was very complex procedure since lots of rework was necessary 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 come to complete task was higher. Defect investigation & troubleshooting was complex.
Electronic Control using Logic Gates: In early 60s electronics dominated the task, electronic logic gates were used for achieving logical operations. they replaced switching devices like relays and contactors inside 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. |
