Educational trainer


The DIGITAL LAB is intended for elementary as well as advance training of digital electronics. The digital lab covers regular digital circuits by solder-less interconnections on breadboard and as well as compatible with all optional modules through use of 2mm brass terminals and patch cords. Various clock generators, logic level input/output indicators and DC regulated power supplies etc. are in-built. The unit housed in attractive en

High level, high quality digital-analog trainer

Includes Two Digital Meters one for 20V Voltmeter and other for 200mA Ammeter

Combines all essential functions of analog and
digital experiment with removable breadboard,
Includes DC power supply function generator, two pulse switches, 8 ohm 0.25W speaker etc.

Interconnected with tie points Nickel plated contact, fitted with all DIP sizes and all components with lead and solid wire. It can be changed and replaced for different purposes and can be connected with demonstration panel. Therefore, it is very convenient for both teachers and students

Two digits of 7 segment LED display

One pulse switch
Push buttons to generate inverting and non inverting pulses supported with de-bounce elimination

Data switches
Toggle switches and corresponding output point. When switch is set at “Down” position, the output is LOW level, contrarily it is to be 'High' level while setting at “Up” position

8ohm/0.5W to be used for load

Four channel adaptor
The two banana sockets and BNC jacks suitable for the trainer to be connected with peripherals

Sixteen bit LED display
Red LEDs separate input terminals. The LED will be lighted up when input is at “High level ”and it will be turned OFF when it is at “No Input” or at “Low level”
