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.

Snap! Crackle! Pop! These are great sounds if you’re crunching cereal or curling up in front of a roaring fireplace on a cool winter evening. However, they are definitely unwelcome if you have just flipped on an electric light switch in your Los Angeles home. While most people can do simple home repairs, electrical problems are much more difficult — and potentially dangerous. At times like this, you’ll need to call on a Los Angeles electrician.

Since 1979 the Electric Connection has been providing electrical service and electrical repairs locally as an electrician in Los Angeles and the surrounding communities. But they offer an additional, very unique electrical service; they are willing to answer your electrical questions and give free electrical advice to homeowners who have questions about their home lighting, electrical rewiring, electrical safety assessments, electrical upgrades, or any other electrical concern. In a way it’s like having your own personal electrician in Los Angeles who will share bits of wisdom and electrical trade advice without charging for an unnecessary electrical service call.

Here’s an example of the kind of electrical help that’s available on The Electric Connection’s website. Suppose a short circuit causes your circuit breaker to flip off. Do you have an electrical wiring issue? Is the circuit breaker overloaded? Is the breaker broken? This Los Angeles electrician’s site walks you through some steps you can take to isolate the problem at no fee. They suggest you think back to what happened immediately before the electrical power went out. For example, if you just plugged in an iron or other appliance immediately prior to the circuit breaker jumping off, unplug the appliance and reset the circuit breaker. If it stays on without any additional electrical power interruptions, the problem is most likely a faulty appliance and not an electrical issue at all.

On the other hand, if the circuit breaker does not work normally, or if you can’t find any specific cause for the break in your electrical power, then it may be time to call a licensed electrician in Los Angeles CA. Everything wears out over time, even circuit breakers, and you may simply need to have yours replaced. Another possibility is that the electrical wiring in your house is not sufficient for the amount of electrical appliances you now have. This situation frequently occurs in older homes which were built before the age of multiple televisions, home computers, entertainment centers, trash compactors and more. In this situation a Los Angeles electrician can add additional electrical wiring to your home or upgrade your electrical panel, bringing it up to speed with today’s highly powered lifestyle.

The Electric Connection’s website is full of other little hints that can help the do-it-yourself homeowner. For example, do you want to change out that old dining room light fixture with a more romantic chandelier that is hooked up to a nice dimmer switch? If so, read the advice on the Electric Connection site to make certain you purchase the correct electrical switch. Do you have flickering lights or electrical outlets that fail to work? The Electric Connection, your Los Angeles electrician, will tell you all of the possible reasons for your problem.

They are also willing to explain things such as the recent electrical upgrades to the National Electric Code that requires special outlets called ground fault circuit interrupters (GFIs) to be installed in electrical outlets which are near water sources, like the bath, kitchen, garage, pool or hot tub. These inexpensive electrical upgrades can be a lifesaver – literally!

Things wear out, including electrical wiring, and codes continually change as improved materials and safety features become available. Do you know the state of our home’s electrical health? If not, you may want to contact a licensed electrician in Los Angeles CA to conduct a free, no-obligation safety check. Your home is not only one of your largest financial investments, but it’s the place of safety you provide your family. Take a little time to give your home a checkup.

When you’re looking on line for electrician Los Angeles, you’ll you can always call The Electric Connection to discuss your electrical projects, to ask any electrical related questions, or to inquire about an electrical estimate.
