RS-232 is one of the oldest and most widely used standards for serial communication between devices, such as computers, modems, and printers.It works by sending data one bit at a time over a cable using defined voltage levels, pins, and signals to ensure both...

As the name suggests, The Signal generator is an electronic equipment which has the ability to produce a Sine-wave signal (Volt) and has a wide range for both frequency/amplitude. It can generate desired signals with a remarkable accuracy. Because of this property, this equipment...

The Programmable Logic Controller, PLC is basically a programmed interface in between the field input elements and the final control element. Advantages of PLC Reduced space : PLCs are completely solid state devices and hence are extremely compact in comparison to hard-wired controller where electro-mechanical...

The internal wiring for Three point starter is shown in the fig below. The three terminals of the starter are marked A, F and L. One line is directly connected to point L which is further connected to the starting handle (arm) through the...

Digital Multimeter is an electronic test equipment which measures the AC/DC voltage and provides the reading in digital numeric mode. It has successfully replaced its age old counterpart , Analog multi-meter, which provides the reading with a pointing needle on a fixed scale. This...

The Frequency counter is a test equipment which is utilised for measurement of the Signal-frequency produced by a Sine wave generating device or an oscillator. It is very simply configured and easy to use. We only need to provide the Signal frequency(to be measured)...
