NOTE:

Two tests each of 25 marks to be conducted as per the schedule given by MSBTE.

Total of tests marks for all theory subjects are to be converted out of 50 and to be

entered in mark sheet under the head Sessional Work (SW).

Rationale:

A diploma engineer has to look after the day-to-day operations, control and maintenance of

controllers used in various automated industrial systems to ensure trouble free working. He should

be well conversant with the various technical aspects of commonly used control components and

control actions in respect of their working and performance. With the above knowledge, he should

also be able to implement innovative ideas of automation wherever necessary.

Programmable Logic Controllers (PLC) have revolutionized and replaced the conventional

industrial automation systems. A single PLC can reliably handle number of complex control actions

in real time with high precision.

Therefore, the electrical diploma engineer must have the basic knowledge of industrial

control components, actions and must be well conversant with the use of PLC therein.

General Objectives:

1) Understand the working of various industrial control components.

2) Use principles of machine control to design simple schemes for control.
