•  Counters 
•  Fault detection  

BASE UNIT - Order Code - M00001 
The Base Unit is used throughout the system M00001. The unit supplies different output voltages suitable for the different lab cards used in the system. The Lab Cards put in slots and are automatically powered via a D-sub connector. 
The base unit is accepted by CE standards. 

TECHNICAL SPECIFICATIONS 
Supply voltage : 220-240V AC 50-60 Hz 
The unit has 6 outputs with following data: 
Output 1 - 3 : DC 12 V / 3 A with LED indication and fuse 
Output 4 - 6: AC 12 V / 3 A with LED indication and fuse 
Dimension: 200 x 300 x 73mm 
Weight: 4 kg Approx

HOUSE ALARM MODULE - Order Code - M00013 
Contains all the functions of a house alarm. The functions of an alarm system are learned step by step so making fault finding more easy to understand. Altogether 8 faults can be simulated. The alarm con­nections are built around normal digital components, e.g. logic gates, comparators, shift registers, counters, different types of switches and decoders. The lab card is connected to the Base Unit.  

TECHNICAL SPECIFICATIONS 
Dimension: 190 x 110 mm 
Weight: 1Kg Approx

COMPONENT SET - Order Code - M00014 

The component set is delivered in a hard plastic box with ESD protection

DIGITAL PCB - Order Code - M00015 
Digital PCB is a printed circuit board with similar functions as the S24 above. The lab card is connected to the Base Unit and is ordered  separately. 

TECHNICAL SPECIFICATIONS 
Dimension: 190 X 110 mm 
Weight: 1 Kg Approx

DIGITAL CONNECTION BOARD - Order Code - M00016
This breadboard is easily connected to 2 contact plugs. The board is suitable for projects where the student connects up circuits on this unit for testing. 
Connection leads 4mm sockets: 4 
Connection lead BNC contact: 1 

TECHNICAL SPECIFICATIONS 
Voltage Ouputs: ( 5V, 12V, and -12V)   
Dimension: 190 X 110 mm 
Weight: 1 Kg Approx 

LAB FLEX SET SHROUDED PATCH CORDS - Order Code - M00011 
Set of 100 leads in 5 different colours,red, yellow, blue and yellow/ green. 5 each of 4 different lengths, 25, 50, 100 and 200 cm. Area: 1.5 mm2 
The pin is protected by a plastic sleeve when the flex is not connected. The plastic sleeve is pushed in to the flex when the plug is connect­ed to the equipment. 

MANUAL FOR 33502A - Order Code - M00017

In the diagram below G1 is used as a data input where G2A=G2B=L. How should A,B and C be set if the data at G1 shall be sent out on the lead connected to Y5? 
As can be seen in the diagram, an extra function has been added, LED that will indicate when the alarm is active. The LED has a self blinking action built into the circuit. 
If the Base Unit is used, the lab-card shall be inserted into the contact plinth where it will receive the correct voltage supply. 
On the lab-card, measurements will be made on an alarm system  constructed from digital circuits. First an easy alarm function and then additional functions as each circuit  has been understood. 
Start by inserting the circuit 74HCT08 in the socket marked IC2 on  lab card 6. If another card is already there, remove it temporarily. 
Remove the jumpers between sockets 1 and 2 at J3, with IC1 and IC2 as shown in diagram. 
All connections are made on the card. 

STORAGE RACK 1 ROW - Order Code - M00010
Storage rack for safe storage of the lab cards. It is constructed of hard plastic and very durable. 

Technical Data: 
Dimension: 150 x 250mm Approx
Weight: 1.4 kg  Approx
