Jlab Export is a leading Digital Trainer Kit to Verify Adders and Subtractors using OR, EX-OR, AND and NOT Gates Manufacturer,and suppliers in India
Digital Trainer Kit to Verify Adders and Subtractors using OR, EX-OR, AND and NOT Gates (code EL-DEECP-1166) is a single trainer for verifying the truth tables of the half adder, half subtractor, full adder and full subtractor. Its panel has a printed circuit of one OR, two AND, two NOT and two EX-OR gates, four logic-input switches on a 5 V supply and two LED outputs. JLab (Jain Laboratory Instruments Pvt Ltd) makes it at its works in Ambala, India.

What Is the Adder and Subtractor Trainer Kit Used For?
Adders and subtractors are where logic gates start doing arithmetic. A half adder gives Sum = A EX-OR B and Carry = A AND B; a half subtractor gives the same Difference = A EX-OR B but Borrow = (NOT A) AND B. The full versions add a third input for the incoming carry or borrow. The gate set on this panel is exactly what a full subtractor needs — two EX-OR gates for the difference, and two NOT gates, two AND gates and one OR gate for the borrow — while the full adder uses the same set without the inverters. Students therefore wire all four circuits on one trainer, step through every input combination with the switches and read the two results (sum and carry, or difference and borrow) on the two LEDs.
The kit fits B.Sc. physics, electronics and computer science labs, engineering and polytechnic digital electronics courses and ITI electronics workshops. Because the ICs sit inside the cabinet and only the sockets are exposed, students build the circuits with patch cords without handling the chips.
Frequently Asked Questions
Which circuits can be verified on this kit?
The half adder, half subtractor, full adder and full subtractor, all built from the OR, AND, EX-OR and NOT gates on the panel.
Why are there two output LEDs?
Each adder or subtractor has two outputs — sum and carry, or difference and borrow — so both can be read at once for every input setting of the four switches.
Should I buy this kit or the single-circuit trainers?
This kit covers all four circuits on one panel, which saves bench space. JLab also lists separate trainers for the half adder, half subtractor and full adder, linked below, for labs that want one circuit per station.
Who manufactures the kit?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, at its works in Ambala, Haryana.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, which manufactures digital electronics trainers and laboratory equipment in India; it was incorporated in 2017 and is based on Hargolal Road, Ambala, Haryana. This adder and subtractor kit is made at JLab’s own works rather than bought from a trader, so colleges, institutes, dealers and importers buy factory-direct, every kit is visually inspected before dispatch, and repeat orders and spares are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — for example Singapore in Southeast Asia, Turkey in the Middle East, Chile in South America, the UK in Western Europe and Hungary in Eastern Europe. For tender purchases see the JLab lab tenders page.
