What is industrial AutomationIndustrial? Automation is a technique through which we make pay human control to machines. In industrial automation machines are programmed to accomplish the tasks which human beings used to achieve. Why it is done? Because of its advantages: Through Industrial automation we will do mass production with less manpower Quality from the method is increased Safety of person & devices are increased More accurate process control Since human intervention is less so reliability with the system is higher Systems operate is low energy, more electronic control so equipment every day 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 each and every step. https://idealprocessandautomation.com.au/ were low 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 in this era was achieved through invention of pneumatic controllers during the early 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 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 highHard 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 task, electronic logic gates were utilised 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 as well as requirements reduced, maintenance requirement reduced & systems were more reliable.
