An understanding of Electricity and Electronics is a primary requirement in all branches of engineering and science education. A challenging and interesting medium is required to hold the attention of students in such a multi-discipline area of study.

Curriculum coverage „ Analogue & Digital

systems

The wide range of work boards available from Feedback meets the majority of needs in academic, vocational and industrial training establishments, and provide a hands-on approach.

„ Electrotechnology

Hardware is supported by comprehensive teaching manuals and, in many cases, detailed ‘Discovery’ software for Computer Assisted Learning is available. Discovery courseware provides the student with on-screen assignments and PC based instrumentation when applicable.

„ Semiconductor devices

The work boards can be used in two ways, depending on the methodology required.

„ Circuit fault finding and

The use of conventional instruments – oscilloscope, frequency and digital multimeters etc. – in making measurements is of importance in the training of service technicians and engineers. The use of PC based instrumentation and courseware offers a reduction on lab requirements for conventional test equipment and is more suited to general electricity and electronic course training needs.

„ Combinational and

Two types of work boards are available, one that requires the circuit to be constructed by the student from discrete components mounted on pin carriers and the other that has pre-mounted components required for a specific area of study.

Discovery software is Feedback’s continuously evolving software package that is used to develop the Discovery Courseware. Discovery courseware presents on-screen student assignments that guide the student through the practical exercises and provide the theory for the subject being studied. The software also provides a PC based instrument toolbox that is made available for specific products which need the use of measuring instruments, such as an oscilloscope, digital voltmeter, frequency meter and spectrum analyser. The instrument toolbox can be launched by the student when instructed to do so from the course instructions. To obtain the full benefit of Discovery courseware the Teknikit Console 92300-1 is required. The console provides power supplies for the various work boards and two BNC inputs conveniently positioned near the consoles upper edge for the PC based instrumentation. The Teknikit console is a robust bench-top unit that provides a platform for both types of work-boards; either self-constructed circuits or pre-mounted types.

Electricity & Electronics

Electricity & Electronics The range of work boards detailed in this section of the brochure fall into two categories: A. Self construction circuit trainers EEC470 series These trainers consist of discrete components mounted on small printed circuit carriers, which vary, depending on the mounted component, from 2-pin devices through to 16-pin integrated circuits. Power semi-conductor components, in many circumstances, are mounted on plug-in heat sinks. Other large components and assemblies have metal or large PCB carriers. This series of products is used with the Electricity & Electronics Constructor Deck EEC470. The carrier-mounted components are plugged into the deck’s spring contact matrix to build the circuit to be investigated. B. Pre-mounted circuit trainers OAT343 through to 13 series products These trainers have pre-mounted components on the circuit boards, conveniently laid out in a circuit format that requires the minimum amount of interconnection. There is very little preparation required by the student to start the assignments, which leaves maximum time for investigation of the assignment objectives. Both categories of work boards require an external power supply that can be provided by one of three options: 1. Bench top mounted open printed circuit board unit, model number 92-445. Ideal for use when training is required with conventional instrumentation. 2. Bench top mounted Teknikit console, model number 92-300. This model can be upgraded to the same specification as the 92-300-1 to include the Virtual Instrumentation. 3. Bench top mounted Teknikit console, model number 92-300-1. In addition to the required power supplies this unit has inputs for virtual instrumentation that in-conjunction with Discovery courseware provides a range of virtual test instruments.

Features „ Choice of training methodology - Conventional or Virtual instrumentation „ Identification of individual components „ Choice of power supply options „ Fully protected supply outputs „ Mixed work board (A and B) student stations possible
