    What is industrial Automation

    Industrial Automation is really a technique where we make give over human control to machines. In industrial automation machines are designed to accomplish the tasks which humans utilized to achieve. Why it is done? Because of its advantages:

    Through Industrial automation we are able to do mass production with less manpower

    Quality in the method is increased

    Safety of man & products are increased

    More accurate process control

    Since human intervention is less so reliability of the system is higher

    Systems operate is low power source, more electronic control so equipment every day 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 utilized to control the procedure at every step. Everything You Need to Know About Industrial Automation Solutions was there at each and every step. Drawbacks were poor output, errors involved in 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 in the logic was very complex procedure since a great deal of rework was necessary to accomplish alteration of logic. So time delivered to complete task changes was very high

    Hard 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 to complete task was higher. Defect investigation & troubleshooting was complex.

    Electronic Control using Logic Gates: In early 60s electronics dominated the process, electronic logic gates were utilized for achieving logical operations. they replaced switching devices like relays and contactors inside 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.
