What is industrial AutomationIndustrial? Automation is really a technique in which we make pay human control to machines. In industrial automation machines are developed 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 from the strategy is increased Safety of man & equipment is increased More accurate process control Since human intervention is less so reliability in the system is higher Systems operate is low energy, more electronic control so equipment life is higher Changes in process logic becomes easier since logics are changed mostly through softwarePrincipal Industrial Automation MNCs L & T ?

Human intervention was there at each and every step. Drawbacks were low quality output, errors involved with human involvement affected compromised safety, wastage of raw material, and accuracy of human action.Then came Pneumatic Control: http://mrmilehy.club/mrmilehyclubgmail-com-or-512-910-7744-text-only-ugly-building-modifier-janitor-austin-texas-addie-allie-jack-golf-flyfishing/krogsgaard34kristensen/activity/911097/ 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 lots of rework was needed to accomplish alteration of logic. So time come to complete task changes was very highHard wired logic control: contactors, relays (for switching), timers and counters (for timing and counting) were utilized 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 task, electronic logic gates were utilised 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 using electronics space and energy requirements reduced, maintenance requirement reduced & systems were more reliable.
