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 devices are used. Higher Life and Reliability : These […]

Neon Tester
A Neon Tester is one of the very popular test equipment of its time. Its basic function is to test if the circuit is live or not. It also measures the approx voltage-scale i.e. from a minimal limit of 110 volts to a maximum limit of 700 volts in both AC/DC supplies. In addition, it […]
Stroboscope
A Stroboscope is also known as strobe. A stroboscope is a test equipment which is utilised for making a cyclical rotating thing appearing to be slow moving or still. In other words, we can say that a Stroboscope is a monitoring and measuring device which uses stroboscopic effects for the observation of rapid periodic motions. […]
Frequency Counter
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) as an input to the Frequency-counter. It does the measurement of […]
Digital Multimeter
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 test equipment may be used to measure the continuity of wire/circuit […]
Three Point Starter
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 overload release. If motor has to be started, we need to […]
What is RS 232 ?
RS 232 stands for Recommended standard number 232. RS-232 ,as an interface, has been a standard from many years for interconnecting a Data Circuit Terminating Equipment (DCE) with a Data Terminal Equipment (DTE). Various forms of RS 232 interface are available in the market. However, being different in design and configuration, they are easy in […]
Signal Generator
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 is utilised to generate desired test-conditions so that it can be […]
