Underwriters Laboratories (UL) is a century old consulting and certification company that is known throughout the world for its stringent levels of certification for electrical devices and components. Industries such as manufacturing, mining, energy, etc. need to follow a certification system for the equipment they procure to make sure their property and personnel are out of harm’s way. Out of the several UL standards that exist, company's that provide electrical components should be UL508A certified.
The 1970s saw the introduction of PLCs or Programmable Logic Controllers, which would forever change the way automation is achieved in industrial environments. Known for its rugged design and scalable implementation, the PLC was adapted by all major manufacturers and to this day is the norm for industrial automation. Allen-Bradley, Omron, Siemens, AEG, etc. became the leaders in PLC manufacturing, and soon the controllers had the processing capability of a computer while withstanding harsh industrial conditions.
Electric Control Panel design is not just about selecting the dimensions of the cabinet, the rating of the enclosure and the IP protection it should offer. It’s actually about creating a design that would ensure comprehensive yet simple control of your plant/machine/process. Planning is the key to proper control panel design, as preemptive rectification of errors is easier than rewiring an established unit. No matter how complex the control requirements are, it’s better to think of the entire design as a continuous process rather than a static entity.
Recent technological advancements have brought improvements to conventional control panel design and fabrication, by a great deal, and if implemented properly can result in lower running cost and higher return on investment. Optimizing control panel design isn’t just part of the modernization process, it is more of a need; one which can bring in a number of positive changes to the conventional working of a plant.
The top five issues currently faced by CEOs include:
- Operational efficiency
- Increasing competition
- Achieving top-line growth
Variable Frequency Drives (VFDs) have slowly become the industrial norm for controlling the output of three-phase AC motors. By varying the voltage and frequency, VFDs achieve smooth and reliable control of the motor’s torque and speed. From motion control applications to ventilation systems to heavy manufacturing, VFDs have become a staple in the industrial landscape.
Industry 4.0, IoT, Digital factory, etc. are some of the concepts that are making headlines in today’s industrial world. Industries around the world are starting to make the shift, and understanding the benefits associated with these technologies, but a mass-upgrade still seems like a long shot. Why?
Variable Frequency Drives form an essential part of any manufacturing plant. Its continuous operation is necessary for maintaining a plant’s output, and any failure results in a chain reaction, effectively bringing the entire industry to a standstill.
Manufacturing industries are always keen on controlling one of the biggest expenses associated with their businesses. Production managers are always under pressure to make sure that their space is managed in the most effective manner possible, and not even an inch of space gets wasted.
Electromagnetic Interference is a common phenomenon in a world which is embedded with electrical circuits. In a nutshell, EMI or Radio-frequency Interference is a disturbance that is generated by an external source like power lines, variable frequency drives, magnetic contactors, etc. effecting electrical circuits in its proximity.
With the increasing requirements for space saving control panels, the risk of Electromagnetic Interference is bound to increase, adding complexity to their designs & shielding techniques.
With new technology advancing the flow of data and connecting every machine with algorithms and sensors, there are so many new possibilities for improving production. But what comes along with all these monitors, tracking systems, sensors, and devices? Large amounts of data.
