What is industrial AutomationIndustrial? Automation is often a technique where we make hand over human control to machines. In industrial automation machines are developed to accomplish the tasks which human beings employed to achieve. Why it is done? Because of its advantages: Through Industrial automation we will do mass production with less manpower Quality in the technique is increased Safety of individual & tools are increased More accurate process control Since human intervention is less so reliability with the system is higher Systems operate is low power, more electronic control so equipment life's higher Changes in process logic becomes easier since logics are changed mostly through softwarePrincipal Industrial Automation MNCs L & T ?

DeltaHow? industrial automation control system Evolved?Initially automation was achieved through manual control, operators utilized to control the task at every step. Human intervention was there at each 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 Pneumatic Control: Industrial automation on 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 necessary to accomplish alteration of logic. So time delivered 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. https://idealprocessandautomation.com.au/ 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 task, electronic logic gates were utilized 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.
