Data Acquisition Card Manufacturer,Supplier and Exporter in India

Product Code : EL-TWL-10430
Jlab Export is a leading Data Acquisition Card Manufacturer,and suppliers in India

The Data Acquisition Card links sensors and switches to a PC through its USB port. It has 4 analog inputs, 2 analog outputs and 22 digital lines, and the user can change what the multifunction pins do. Two unity gain amplifiers take weak sensor signals, and every wire goes to a removable screw terminal.

Interfacing Practicals with the Card

Students start by wiring a Temperature Sensor to an analog input and logging a beaker of hot water as it cools. The sensor gives 10 mV for each degree Celsius, so the class converts volts to temperature in the software and draws the cooling curve.

Next, they set a voltage on one analog output, check it with a Digital Multimeter and feed it back into an analog input to compare the three values. The digital lines suit a traffic light sequence with LEDs and push buttons. Students who know VB6 or VB.net can write that program themselves.

Frequently Asked Questions

How many channels does the card have?
It has 4 analog inputs, 2 analog outputs and 22 digital lines. The digital lines can work as inputs or outputs, because the user sets the job of each multifunction pin.

What do the two unity gain amplifiers do?
A unity gain amplifier passes a voltage on at the same size, a gain of one, but draws almost no current from the source. A weak or high resistance sensor feeding it therefore keeps its true output instead of being pulled down by the input.

Can I write my own software for it?
Yes. The card works with the supplied PC software, and users can also write programs in VB6 or VB.net to read the inputs and set the outputs. That suits projects in instrumentation and computer interfacing.

Is this card or the SD card system better for my lab?
Choose this card for live work with a PC and when you need analog outputs for control. The Data Acquisition System with SD card has 8 analog inputs and stores readings on its own memory card, so it can log without a PC.
