Early Christmas morning in Stamford, Connecticut, the fire department rushed to the aid of Madonna Badger’s family as their home was engulfed in flames. The simple act of discarding ashes from the fireplace turned deadly when those ashes were not fully extinguished, sparking the blaze from outside the home. The heartbreaking news that both of Badger’s parents and her three young daughters perished in the fire turned what would normally be a joyous holiday into a time of mourning for friends, family, and community members in Stamford. Our hope, at ElectricMan Inc. is that this sad story will help drive home the message that smoke detectors are the most important safety feature that you can have in your home.

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.

We’ve recently added four new CAN Bus LED festoon bulbs. These 6418, 6451 festoon bulbs are designed to communicate with vehicle CAN Bus computer systems and prevent “bulb out” error messages. They can be used for numerous applications, such as map lights, dome lights, vanity lights, trunk lights, and footwell lights.

Powerful cool white LEDs are mounted to one side of the bulb’s printed circuit board for direct illumination without wasted light, and an LED-cooling heat sink is incorporated into the back of the board. These error-free bulbs are designed to last 25 times longer than incandescent bulbs.

FAQ post.

A gas furnace is an economical way to heat your home, and a yearly furnace tune-up is essential to keep your appliance at peak performance. The more efficient your furnace, the less energy it uses. It’s better to get yearly service, while the weather is still warm, than to be faced with no heat on a cold Colorado night. In the long run, you’ll save money with periodic tune-ups. Here are some of the ways an annual visit from a Colorado furnace repair technician can cut down on your costs.

Minimizes Repairs

A furnace tune-up reduces the incidence of repairs. Think of it as preventative medicine for your home. With regular checkups, you nip problems in the bud and avoid costly emergency service. Technicians clean and inspect your appliance. If anything is in need of maintenance, it can be done on the spot or scheduled for later.

Keeps Your Home Safe

Keeping your family safe is even more important than saving money, but sometimes the two things go together. While heating systems are not hazardous under normal conditions, a gas leak in your home leads to dangerous conditions. Evacuating to a hotel, either because of a leak or because of no heat during frigid conditions, is expensive. During a furnace tune-up, a technician will check that the combustion process is precise and safe.

Proper Airflow

The correct airflow is essential to the function of your heating system. If the airflow is faulty because it’s restricted, it puts a strain on the furnace and can shorten the life of your appliance.

Improved Efficiency

A clean, well-maintained furnace performs better than a dirty one. Efficiency leads to less wasted energy, and that translates into lower bills for you.

Maintains the Warranty

Most manufacturers void a warranty if the furnace doesn’t get regular maintenance. Protect your investment by following the manufacturer’s suggestions for tune-ups
