Jlab Export is a leading Logic Gate Circuit Trainer and Digital Computer-II [Bread Board Model] Manufacturer,and suppliers in India
Logic Gate Circuit Trainer and Digital Computer-II [Bread Board Model] (code EL-DEECP-1191) is a breadboard digital electronics trainer on which students wire their own logic circuits — from gates and De Morgan theorems to flip-flops, counters, shift registers, encoders and multiplexers — in college, polytechnic and ITI labs. It has regulated 5 V DC/1 A and ±15 V DC/150 mA supplies, 10 SPDT logic inputs, a 1 Hz clock and 3 seven-segment displays. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Logic Trainers?
| Trainer | How circuits are made | Power supplies | Inputs, outputs and extras |
|---|---|---|---|
| This trainer (EL-DEECP-1191) | Students wire circuits on the front-panel breadboard | 5 V DC, 1 A and ±15 V DC, 150 mA | 10 SPDT logic inputs with LEDs; 10 output indicators; 1 Hz clock; 3 seven-segment displays |
| Logic Gate Circuit Trainer using TTL IC | TTL ICs fitted inside the cabinet; connections at front-panel sockets | 5 V DC, 1 A, short-circuit and overload protected | 10 debounced logic inputs; 10 red LED outputs; 1 Hz clock |
| Analog and Digital Trainer Bread Board Type | Two breadboards | ±5 V; ±15 V fixed; variable supply | Logic input and output; clock pulse; function generator 1 Hz to 250 kHz; 6 variable resistors |
Choose this trainer when students should build each digital circuit themselves and see results on displays as well as LEDs. The TTL IC trainer suits quick truth-table verification with ready-wired ICs, and the analog and digital trainer suits courses that also cover amplifiers and signal circuits.
What Is the Breadboard Logic Trainer Used For?
The trainer covers the core practicals of a digital electronics course. Students place logic ICs on the breadboard, set input levels with the SPDT switches (the input LEDs confirm each level) and read results on the output indicators. They verify gate truth tables and Boolean identities, prove De Morgan’s theorems by comparing the two sides of each identity, build half and full adders and subtractors, and then move to sequential circuits: flip-flops, counters and shift registers driven by the 1 Hz clock, which is slow enough to watch each state change. Encoders, decoders, multiplexers and demultiplexers complete the combinational set, and the seven-segment displays show counter or decoder outputs as decimal digits through a BCD-to-seven-segment decoder.
The 5 V, 1 A supply runs TTL logic, while the ±15 V rail allows dual-supply parts such as op-amps in interface circuits. Because the circuits are wired rather than pre-built, the trainer also suits mini-projects and practical examinations in B.Sc. electronics and physics, engineering diplomas and ITI electronics trades. Switch off before changing wiring, check IC orientation and supply pins before power-up, and keep leads short and tidy.
What to Specify When Ordering
- ICs, components and connecting wires — this listing does not say whether they are supplied; ask for a component set matched to your experiment list.
- Mains supply — give your supply voltage.
- Quantity — the minimum order is 10 units; many labs plan one trainer per student group.
- Companion trainers — add ready-wired trainers for flip-flops or shift registers if you want fixed-circuit versions as well.
Frequently Asked Questions
Which experiments can be performed on this trainer?
Truth tables of logic gates, Boolean identities and De Morgan theorems, adders and subtractors, flip-flops, counters, shift registers, encoders, decoders, multiplexers and demultiplexers, each built on the breadboard.
What power supplies does it have?
Two DC regulated supplies: 5 V DC at 1 A and ±15 V DC at 150 mA.
How are inputs applied and results shown?
Ten logic inputs are set with SPDT switches, each with its own LED indicator. Results appear on ten logic output indicators and three seven-segment displays, and a 1 Hz clock drives sequential circuits.
Are ICs and components included?
The listing does not state this. Ask JLab to quote a component set, ICs and connecting wires with the trainer so each bench is ready for the experiments you run.
How does it differ from the Logic Gate Circuit Trainer using TTL IC?
On this model students build circuits on a breadboard and also get a ±15 V supply and seven-segment displays. The TTL IC trainer has its ICs fitted inside the cabinet, with connections at sockets and ten debounced inputs.
Who manufactures this trainer?
JLab, the trading name of Jain Laboratory Instruments Pvt Ltd, makes it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of digital electronics trainers and laboratory equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The breadboard logic trainer is built in JLab’s own works rather than bought from a trader, so colleges, training institutes, dealers and importers buy factory-direct, every unit is visually inspected before dispatch, and repeat orders and replacement parts are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — for example Ireland in Western Europe, Peru in South America, Botswana in Southern Africa, Guinea in West Africa and Hong Kong in East Asia. For institutional purchases, see the JLab lab tenders page.
