Overview of the Arduino Boards
The Arduino Uno is the current incarnation of the original Arduino board. It is the most common Arduino board and is generally what people mean when they say they are…
Introduction to Arduino Board (Basic knowledge for newbies)
What Is Arduino? The term Arduino is used to describe both the physical Arduino board (of which the most popular type is the Arduino Uno) and the Arduino system as…
How to Install arduino IDE (Latest)
The software that you use to program the Arduino is called the Arduino Integrated Development Environment (IDE). If you are a software developer and accustomed to using complex IDEs like…
Manufacturing process of forming plastic
Forming plastic is the process of transforming a specified material into a desired shape. Raw plastic, or resin, is usually in the form of pellets, powder, liquid components, or sheets.…
Control transformers in a control circuit
Most industrial motors operate on voltages that range from 240 to 480 volts. Magnetic control systems, however, generally operate on 120 volts. A control transformer is used to step the…
What is Mercury Relays
Mercury relays employ the use of mercury-wetted contacts instead of mechanical contacts. Mercury relays contain one stationary contact called the electrode. The electrode is located inside the electrode chamber. When…
What is Motor Starters (Basic knewlegde for newbies)
Motor starters are contactors with the addition of an overload relay. Because they are intended to control the operation of motors, motor starters are rated in horsepower. Magnetic motor starters…
Mechanically Held Contactors and Relays
Mechanically held contactors and relays are often referred to as latching contactors or relays. They employ two electromagnets to operate. One coil is generally called the latch coil and the…
What is Contactors (basic knowledge for newbies)
Contactors are very similar to relays in that they are electromechanical devices. Contactors can be obtained with coils designed for use on higher voltages than most relays. Most relay coils…
Electromagnetic Relay Construction
The construction of the electromagnetic part of a relay or contactor greatly depends on whether it is to be oper ated by direct or alternating current. Relays and contactors that…
