Advantages of Programmable logic controller
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 […]
Programmable Logic Controller
A Programmable Logic Controller can be defined in many ways. It can be defined as a program controlled electronic equipment with a reprogrammable memory for storing a set of commands which is used for executing exact tasks like logical, arithmetic, timer, counter, and furthermore controlling different processes or machines with the help of analog/digital through digital […]
Series Motor Starter
A face plate/drum type controller is used for starting the series motor. This controller can also be used to control the speed of a series motor as well as to reverse the direction of its rotation. It is commonly known as Series motor starter. As the operator has to monitor the operation of motor continuously, […]
Direct online starter
The most simple and basic type of starter for motors (induction motor) is the Direct Online starter. The Direct on line starter contains an ON/OFF switch and an OLR. Here, OLR stands for overload relay for protection against excessive load current. The selection of switch depends upon the operator’s requirement. Generally, the switch which is […]
Auto Transformer Starter
An Auto transformer starter basically uses an auto-transformer to reduce the voltage applied to a motor during its start. As we know that the starting of big motors which are used for prolonged periods exert large current in the circuit. Due to this, a voltage drop occurs which may damage other electrical equipments which are […]
Star Delta Starter
Star Delta starter comes under the category of starters using reduced voltage method for starting the motor. Just like all other starters, the basic aim to use this starter is to decrease initial high starting current generated by the motor at the starting procedure. It is used for the purpose of limiting the voltage drop […]
Methods of Measurement
Measuring instruments may be defined as device for determining the value or magnitude of quantity or variable.To know about ‘Measuring instruments’ in detail, visit https://electricalfundablog.com/blog/measuring-instrument/665/. Here in this post, we will learn about the methods of measurement. The methods of measurement may be broadly classified into two categories. Direct Methods of measurement. In this method, […]
Null Modem cable
Null Modem Cable. A null modem cable is a form of RS-232 standard where the transmit and receive lines are cross linked. Normally a straight through serial cable is used with this kind of adapter. The adapter is pre configured with the necessary cross links. In some cables, handshake lines are also cross linked. The […]
Interface
An Interface is a common shared medium across which two different components of a computer system can exchange data or information. There are basically two types of interface: Hardware Interface Software Interface Majority of equipments which do processing of data contains a relatively restricted capability in terms of transmission of data. It is very uncommon […]
