What is industrial AutomationIndustrial? Automation can be a technique through which we make give human control to machines. In industrial automation machines are designed to accomplish the tasks which individuals employed to achieve. Why it is done? Because of its advantages: Through Industrial automation we could do mass production with less manpower Quality of the product is increased Safety of man & devices are increased More accurate process control Since human intervention is less so reliability of 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 softwarePrincipal Industrial Automation MNCs L & T ?

Human intervention was there at each and every step. Drawbacks were low quality output, errors linked to human involvement affected compromised safety, wastage of raw material, and accuracy of human action.Then came https://idealprocessandautomation.com.au/ : Industrial automation on 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 from the logic was very complex procedure since lots of rework was required to accomplish alteration of logic. So time taken 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 chosen 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 usage of electronics space as well as requirements reduced, maintenance requirement reduced & systems were more reliable.
