Monostable and Free Running Multivibrators using IC 555 Manufacturer,Supplier and Exporter in India
Product Code : EL-SOM-1154
Jlab Export is a leading Monostable and Free Running Multivibrators using IC 555 Manufacturer,and suppliers in India
Monostable and Free Running Multivibrators using IC 555 (code EL-SOM-1154) is a 555 timer trainer whose monostable section is designed to study the output wave shape of a monostable multivibrator driven by an external trigger. A 5 V DC regulated supply is available on sockets, the IC 555 sits inside the cabinet with its connections at sockets, and the circuit diagram is printed with the components on the front panel. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab IC 555 Trainers?
| Trainer | Details given in its listing |
|---|---|
| This trainer (EL-SOM-1154) | Monostable wave-shape study with an external small-duty-cycle trigger; 5 V DC regulated supply on sockets; printed circuit diagram; free-running circuit named in the title |
| Monostable Multivibrator using IC 555 | In-built power supply; set of patch cords; user’s manual |
| Astable Multivibrator using IC 555 | Free-running circuit for wave shape and frequency; IC 555, resistors and capacitors at sockets; 5 V DC regulated supply |
| Monostable and Free Running Multivibrators using Transistors | Transistor version; square, rectangular and pulse waves |
What Is the Monostable and Free-Running 555 Trainer Used For?
In monostable mode the 555 rests with its output low. Each time the trigger input is taken low, the output goes high for a fixed time set by the timing resistor and capacitor and then drops back, whatever the length of the trigger. For clean results the trigger must be shorter than the output pulse, which is why the listing calls for a square wave of small duty cycle. Students feed the trigger from a function generator, compare trigger and output on a dual-trace oscilloscope and see that the pulse width stays fixed while the trigger rate changes. In free-running (astable) mode the 555 needs no trigger at all and produces a continuous rectangular wave. Both modes are core timer practicals in B.Sc. electronics, diploma and ITI/TVET labs.
What to Specify When Ordering
- Quantity — the minimum order is 10 trainers.
- Confirmation of the free-running section, which the listing names but does not describe.
- A function generator for the trigger and an oscilloscope, if they should be quoted with the trainers.
Frequently Asked Questions
What trigger signal does the monostable section need?
A square wave of small duty cycle, connected at the trigger-input provision. A function generator is the usual source; it is not part of this listing.
Does the trainer also cover the free-running multivibrator?
The title names both circuits, but the listing describes only the monostable section, so ask JLab to confirm how the free-running circuit is provided before you order.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer in India of electronics trainers and teaching-lab instruments, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The trainer is built at JLab’s own works rather than bought in, so institutions, dealers and importers deal directly with the maker for quotations, repeat orders and spares. JLab exports worldwide and ships to buyers in every region — for example Canada in North America, Guyana in South America, Malawi in East Africa, Norway in Northern Europe and Nigeria in West Africa. Tender information is on the JLab lab tenders page.
Trigger Sources and Related Trainers
- A.F. Oscillator Function Generator Cum Digital — an audio-frequency oscillator and function generator with a digital frequency meter, for driving the trigger input.
- Dual Trace Oscilloscope — shows trigger and output together.
- Astable and Monostable Multivibrator Trainer — another trainer for free-running and one-shot circuits.
