Two atoms were walking down the street one day, when one of them exclaimed, “Oh no – I’ve lost an electron!” “Are you sure?” the other one asked. “Yes,” replied the first one, “I’m positive.”

I have heard that joke at least ten times and it is still over my head. Maybe it all boils down to the way I view things, usually on a more metaphysical level, or as my sister would say, “out there and far fetched.” I totally understand the idea behind quantum physics; the idea that a researcher’s views and expectations influence the outcome of their experiments makes total sense. It gives those scientists power over what they do. On the other hand, when it comes to comprehending electricity, I just get lost. The subject is so hard to grasp; the only thing I know for sure is that I am very dependent on it. It seems to have all the power, no pun intended. I challenge you to gain better knowledge than I have in the journey that takes you around in a circle between the words electric, electric charge and electricity, each one’s definition leading back to the others.

Thank goodness for those who understand what I don’t. Another subject that seems to be connected to electricity, but don’t ask me to explain, is the internet. All I had to do to find an electrician in Beverly Hills, was search for “electrician Beverly Hills CA” and some sort of “feelers” out there in a hidden territory gave me The Electric Connection. To me it does not seem so far fetched that in a few years I may only have to think “electrician Beverly Hills” and one will show up at my door. Shoot – that was almost what happened, now that I think about it. The only difference was the inclusion of a phone call.

When the Beverly Hills electrician from The Electric Connection finished his work at my home the next day, I knew that he understood this complex subject. He probably gets the internet too. I did not end up with funny shoes or new exercise equipment, but I do have new electrical outlets, two ceiling fans installed and some landscape lighting that I have wanted for ages. This electrician in Beverly Hills even did his best to explain electricity to me, which included what he knew about electric eels. I am sure he noticed the glazed look on my face, but at least he tried.

There is just so much to learn here in one short life, or even in several for that matter. I have learned that we cannot be experts at everything, but we can sure appreciate those who are. I may not know fully understand electricity or cyberspace, but I do know great customer service when I see it, which is exactly what everyone should expect from their local Beverly Hills electrician.

A Programmable Logic Controller (PLC) receives information from one or more inputs. This semiconductor control device processes the information based on a software program. Finally, it sends an output control signal. The microprocessor based control system performs functions such as timing, logic, sequencing and others. The PLC follows instructions from an operator-defined program.

These intelligent systems provide reliable, high-speed monitoring and control of processes in automated applications. In addition, they are easy to program and configure.

Once the program updates the output, the CPU starts over and the cycle repeats again. The cycle depends on the number of inputs, outputs, and size of the program, while the action will depend on the inputs coming from a variety of sensors.

The input sensors include components such as switches, proximity sensors, photoelectric sensors, pressure switches, level switches, encoders and temperature sensors, while the output devices include actuators, relays, switches, and many more.

PLCs rely on software programs that help them in making the necessary decisions. The PLCs are programmed through a variety of tools, which may differ in ease of use, appearance, and complexity. The most commonly used PLC programming language is Ladder Logic, a graphical software that uses common electrical symbols. Other languages include Function Block Diagram (FBD), Sequential Function Chart (SFC) and Structured Text (ST).

The programming is done on the device such as a computer or handheld device after which it is transferred to the PLC memory using a communication interface.

Selecting a suitable PLC that will address your current and future needs can be a challenge, especially with the large number of different PLCs on the market today. The available PLCs have varying capabilities, physical sizes, complexity, cost, power requirements, scalability and other parameters. Therefore, it is necessary to determine the correct programmable logic controller for your specific application. Special systems can be designed for use in harsh environments.

The Programmable Logic Controller has revolutionized and simplified controls in automation and industrial applications. PLCs are easy to install, wire, program and modify to suit changing application requirements. These control systems are usually available in a wide range of sizes that ensure finding exactly what you need for any application.

Indoor Generator Provides 20,000 Watts of Stored Renewable Energy to a Ranch Home, Even When All External Power Supply is Unavailable

Dallas, TX  December 30, 2011– Doug Kerr is the proud owner of a stretch of land located in the rural area of Kaufman County (Texas) where the air is fresh and the hustle and bustle of city life is non-existent. One thing Doug’s land doesn’t have, however, is a city power grid. Traditionally, to gain access to power in an area that hasn’t already been included on the electrical grid, you can pay the local electrical provider a large sum to run new electrical service to your location, or be forced to use noisy, polluting, and high-maintenance fuel-powered generators.
