The Series 782 Electromechanical Ice Cube Relay is a full-featured DPDT relay that can be used to switch two different devices with a single trigger. With a ratting of 15 amps, the relay can be used to stop and start small fans, motors, and pumps directly. It features a flag status indicator and a LED status lamp to let the user know when the relay is activated. In order to differentiate between AC and DC actuated models the push-to-test button is color-coded. For testing the operation, a removable lock-down lever holds the test button in place. The clear plastic housing gives a view of the contacts, and there is a removable I.D. tag for labeling the circuit.

I need help.Im doing my research on (1940's and how computer impacted american society..) WHAT WOULD U PUT AS INTO AND IS MY BACKGROUND GOOD ?(FEEL FREE TO ADD....) TRUST ME I wouldnt mind...;) My Into/Background due tommorow.I honestly need help! I begin with intro then workmyself to background?? I did my into can someone help me with my Intro...Im talking about the first computer ENIAC...umm..different computers used during 1940's how computers used to help military.communication...and research... helppp. Life without e-mail, calculators, or cell phones would impair society from the bottom to the top, from the president to the local delivery boy, from a doctor to a cashier, from a general to a soldier. Since the invention of computers the way people research, communicate and wage war was drastically altered. It all started with the Atanasoff Berry computer which calculated and solved linear equations. This primitive computer, first tested by Dr. Atanasoff and Clifford Berry in 1942 is considered to be the first computer ever built. The Atanasoff-Berry computer was followed by the more widely known ENIAC computer created in 1945. The ENIAC was successfully used in World War II for calculating artillery firing tables. Following the Demise of World War II, the technology funded by the government filtered into civilization life forever changing the structure of society.
And got the following answer:
Computer Technology and its Early Impact on American Society Computers, perhaps, are the most important innovation in the history of the world to date. Without modern computers today, the world would not be able to function in the manner of which people today are accustomed. Americans take for granted their ability to go to a machine to withdraw cash, scan large amounts of groceries through a barcode scanner, or type a report on a word processor. It is computers that make these tasks, which most Americans take for granted, possible. These computers emerged in the mid- twentieth century and, by the early 1980s, would become a part of mainstream American society. Essentially, the modern infiltration of computers in American society is the continuing result of what many consider a revolution. Like political revolutions and industrial revolutions, the computer revolution is not one change or a few, small changes, but rather a complex integration and interrelationship of almost innumerable changes. To understand how computers changed American society, some background on the development of the earliest computers is necessary. The origins of modern electronic computing began as a result of the scientific emphasis behind World War II, especially the need for mathematical computation . The Moore School of Electrical Engineering at the University of Pennsylvania was the birthplace of the first electronic computer . This computer was called the Electronic Numerical Integrator and Computer, or ENIAC , which was completed in 1946 by John Mauchly and John Prosper Eckert . As large of an achievement as the ENIAC was, it was hardly an ideal computer. The ENIAC used approximately 18,000 vacuum tubes . The ENIAC also used approximately 70,000 resistors, 10,000 capacitors, 6000 switches, and 1500 relays . Simply put, the ENIAC relied on an enormous amount of electronic parts and electricity. This made the ENIAC rather prone to failure. The ENIAC also had the problem of limited information storage . This problem was addressed by the development of the Electronic Discrete Variable Automatic Computer, or EDVAC. The EDVAC was the first computer to use the concept of information stored in memory. The EDVAC would also use binary numbers instead of decimal numbers, which increased its computation abilities threefold . The EDVAC was eventually completed in 1952 and its internal memory design paved the way for all future computers . By 1952, even as the earliest computers were still evolving, the computer created perhaps its first big moment in the national limelight. The computer company Remington Rand convinced the television network CBS to use their computer, the UNIVAC, to predict the winner of the presidential election between Dwight Eisenhower and Adlai Stevenson . Stevenson was the early favorite in the polls, but the program used by the UNIVAC predicted a landslide victory by Eisenhower. On election night 1952, a mock UNIVAC was setup at UNIVAC headquarters with CBS news anchor Walter Cronkite reporting at CBS headquarters. The event, originally a publicity stunt by UNIVAC, was seen all across the United States . The UNIVAC predicted the eventual Eisenhower victory by a 438 to 93 vote margin, which nearly matched the actual outcome of 442 to 89 . The American public now had its first taste of the potential power of computer technology in their everyday lives. Besides the early recognition computers received by the prediction of a presidential election, it was becoming increasingly necessary for a tool that could organize huge amounts of statistical information, especially for business uses. The Social Security Administration of the United States government was the first federal bureaucracy to require the use of computers. The SSA originally used electromechanical devices that processed information on punched cards . In 1954, amendments to the Social Security Act required that a permanent record of every American's annual income and a cumulative total of all individual be tallied . With 320 million punch cards needing to be processed, the SSA was in danger of being bogged down by such a huge amount of information processing. The IBM 705 computer, which was specially designed for the SSA, came to the rescue. Instead of using punched cards, the IBM 705 used reels of magnetic tape to store information. Each tape could store Social Security information of 60,000 individuals . In the late 1950s, vacuum tubes were replaced by transistors as the primary parts of computers . Transistors, unlike their vacuum tube predecessors, were much smaller and generated much less heat ; consequently, transistors were much more efficient. A new type of memory, called magnetic-core memory, increased access to stored information . In the early 1960s, internal computer parts shrank
The electromechanical relay testing perform very properly with different applications that happen to be distinct to energy distribution and protection. The relays come with wide adjustment ranges using a scale that may be simple to read either in 3 or 4 digits according to the model. These electromechanical relay testing support in increasing the flexibility with the applications, lessen the overall power and upkeep expenses. You will discover relays that are made use of for basic purposes which are available in dependable designs with quick replacement selections. And you can find models which might be utilised for industrial applications and heavier duty applications that operate on massive loads. These items are produced to meet the lifetime industrial control demands of your applications.
Their newest goods are the Time counter, Timer Delay, electromechanical relay testing, Rapid Connect Couplings, Electronic Motor Couplings, Aluminum Couplings, Morse Couplings and different other people. The web site presents a detailed description of each and every model in many categories of electromechanical relay testing couplings and sensors. These solutions are extremely helpful for high-risk applications. The electromechanical relay testing are also out there with features like multiple timing ranges and functions. The firm is at present trying to find agents and dealers who can promote and sell their factory created goods.
