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.
Improving Efficiency & Speed in the Automation Industry
Parallel programming has always created issues for the the programming industry. Coming towards the pragmatic workings of the automation industry, the processes are often trapped within a loop that makes use of the same block of code iterative. Software configureable I/O is an up and coming concept regarding automation that can greatly improve the efficiency and speed of a process.
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.
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.
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.
Every year, the world discharges 2 million tons of sewage, industrial and agricultural waste, polluting waterways and directly killing 1.8 million children from waterborne diseases. This statement alone should be enough to encourage an effective framework for increasing a country’s capacity to treat wastewater for a healthier environment.
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.
Automation not only cuts costs and saves time but instills reliability and precision within the system that has immediate and long-term benefits. Today home automation or hobby projects often conjure images of teenagers working on Arduino, Raspberry Pi and PIC, but the true struggle to make industries and large-scale systems independent began more than five decades ago.
Electrical control panel design basics is a vast field, dotted with problems pertaining to management, visual appeal, reliability and safety. The design basics for control enclosures that house various components from Programmable Logic Controllers (PLCs) to high-voltage relays is dependent on several parameters, however, keeping down the cost is one that can’t be sidelined at any time.
