Electricity has been readily accepted for residential, commercial and industrial usage at an unprecedented rate. Today, almost all modern manufacturing plants rely on electric power as a utility for fabrication & production processes. Due to the level of complexity & interconnectivity of the current system, even seconds’ worth of offline time can result in monetary & material loss.
Any electrical system, no matter how small, will generate heat since it will contain a resistive element in one form or another. As the size of your load increases, so does the quantity of heat produced. Your system might be able to bear the increasing temperature initially but at some point, it will give in and the result can be fatal.
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.
Testing the transformers in your factory is essential to keeping your production running safe and efficiently. The following are 12 standard tests to check your transformers:

Soft Start and VSD: Basic Principles
Electric motors do not just switch on and off from a dead stop to operating speed. Rather, these motors get turned on by accelerating relatively slowly until they reach their desired speed. This speed “ramping” is necessary to keep the motors from burning out due to overloading, and the most common way to achieve this ramping effect is to drive the motors with either a soft starter or variable speed drive (VSD).
Topics: Industrial Automation
Fuses are an overly abundant electrical component, and they come in all sorts of shapes and sizes. This would make picking out a replacement easy, except there are so many types of fuses out there that the likelihood of two aesthetically identical fuses having the same operating specs is pretty low. This identity crisis can lead to mistakes in selecting a new or replacement fuse, which puts workers and equipment at risk.
Ladder Logic 301: One Shots
Through this series on ladder logic, you have been given an introduction to the basics of ladder logic 101 and you have seen some of the upper level conceptual ideas behind the use of ladder logic in PLC systems. To end the series for now, it is necessary to add one more concept to the list, and that is the use of one shots to control signal durations.
Machine Safety in Automation
As automation becomes more integrated into industries, safety features and requirements continue to change. Automation takes workers further away from working on the floor, but it also makes it easier for people to work alongside machines.
Control system integration is key to improving industries and automation. Automation has been increasing the use of more machines to complete tasks alongside of workers, which improves efficiency and quality of production. However, these machines are dangerous and it is vital to have a control system in place to turn off and control the machines. In the past, these control panels were separate for each machine, but newer technology is moving towards integrated larger control systems so more machines can be shut down or controlled from a central location.
In the last ladder logic article, Ladder Logic 201, we began to see some of the interaction between PLCs and ladder logic, and that will continue now with a quick introduction to ladder and PLC memory organization and its benefits.
