Educational Goals

The course is designed to provide the theoretical and practical knowledge on the principles of classical industrial automations. Emphasis is given on relay based automations, while some reference is made to PLC automations. Upon successful completion of the course the student will be able to:
1. Have a good knowledge of the material, elements and components used in Classical Industrial Automations (CIA) and be able to recognize them.
2. Have a clear image of the dangers involved in the construction, operation and maintenance of CIAs.
3. Design a simple, typical industrial automation system.
4. Read and design in detail the auxiliary circuit of a CIA and specify the power circuit.
5. Produce a Bill of Materials.
6. Estimate the cost of materials and cost of constructions of an automation panel.
7. Locate and solve a malfunction in an automation panel.
8. Follow up on the technological advancements in fields such as PLCs, industrial electrical components, etc.

General Skills

Practical application of theoretical knowledge

Teaching Methods

Lectures for the theoretical part. If the number of attending students allows it there will be visits to the CIA Lab, during the Exercise Lessons. Otherwise the exercises will be explained in class. Projected Presentations, E-mail and facebook communication, Online Synchronous and Asynchronous Teaching Platform (moodle).
