Electricity & Electronics


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

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

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

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

The use of conventional instruments – oscilloscope, frequency and digitalmultimeters etc. – in making measurements is of importance in the trainingof service technicians and engineers. The use of PC based instrumentationand courseware offers a reduction on lab requirements for conventional testequipment and is more suited to general electricity and electronic coursetraining needs.

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

Discovery software is Feedback’s continuously evolving software package thatis used to develop the Discovery Courseware.

Discovery courseware presents on-screen student assignments that guide thestudent through the practical exercises and provide the theory for the subjectbeing studied. The software also provides a PC based instrument toolbox thatis made available for specific products which need the use of measuringinstruments, such as an oscilloscope, digital voltmeter, frequency meter andspectrum analyser. The instrument toolbox can be launched by the studentwhen instructed to do so from the course instructions.

To obtain the full benefit of Discovery courseware the Teknikit Console 92-300-1 is required. The console provides power supplies for the various workboards and two BNC inputs conveniently positioned near the consoles upperedge for the PC based instrumentation.

The Teknikit console is a robust bench-top unit that provides a platform for bothtypes of work-boards; either self-constructed circuits or pre-mounted types.

The range of work boards detailed in this section of the brochure fall intotwo categories:

A. Self construction circuit trainers EEC470 seriesThese trainers consist of discrete components mounted on small printedcircuit carriers, which vary, depending on the mounted component, from 2-pindevices through to 16-pin integrated circuits. Power semi-conductorcomponents, 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 ConstructorDeck EEC470. The carrier-mounted components are plugged into the deck’sspring contact matrix to build the circuit to be investigated.

B. Pre-mounted circuit trainers OAT343 through to 13 series productsThese trainers have pre-mounted components on the circuit boards,conveniently laid out in a circuit format that requires the minimum amountof interconnection. There is very little preparation required by the student tostart the assignments, which leaves maximum time for investigation of theassignment objectives.

Both categories of work boards require an external power supply that canbe 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 92-300-1to 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 virtualinstrumentation that in-conjunction with Discovery courseware providesa range of virtual test instruments.
