What is Automation?

Programmable Logic Controllers:-

In manual control,an operator many periodically read the process temperature and adjust the heating or colling input up or down in such a direction as to drive the temperature to its desired value. In automatic control measurement & adjustments are made automatically on a continuous basis. Manual control may be used in non-critical application where major process upsets are unlikely to occur, where any process conditions occur slowly & in small increments and where a minimum of operator attention is required


What is Automation?

Making products under the control of computer and programmable controllers is know as Industrial Automation.Manufacturing lines as well as stand-alone machine tools (CNC machines) and robotic devices fall into this category.Automation is delegation of human control functions to technical equipment for increasing productivity,better quality, increasing safety in working conditions reducing manpower & cost.


What are are the different components used in Automation?

The components of automation system include
1) Sensors for sensing the input paramerers
2) Transmitters for transmitting the raw signal in electrical form
3) Control system which include PLC,DCS& PID controllers
4) Output devices such as actuators,drive,control valves,solenoid valve,coils,indicating lamps.
