For those who work in electrical design, a prominent concern is circuit protection. While a lot of circuit protection technologies exist, it is most common to guard against overcurrent situations. Overcurrent protection can be achieved by incorporating fuses or circuit breakers along the primary power feed. But which of these devices do you use for branch…
Photoelectric, proximity and capacitive sensors are used in a wide variety of machines and industrial equipment, but selecting the best sensor for the job can be confusing. This blog post and the accompanying articles will help you sort out the best sensor for your application. During sensor selection, it’s important to understand sensor requirements and specifications…
What is a Fuse? Fuses are sacrificial devices used to protect much more expensive electrical components from the damaging effects of overcurrent. They consist of a low-resistance metal or wire that is used to close a circuit. When too much current flows through the low resistance element of the fuse, the element melts and breaks…

When wandering the plant floor, keep an eye out for energy wasting machines. Those running conveyors, rattling pumps and hissing air lines on idle equipment not only raise the decibel level in the plant—they also waste energy. With proper monitoring and analysis, machine energy use can be optimized, and these energy saving measures will also improve…
So the story starts with you looking at a plant full of equipment, some new, some old, with the operators working hard to meet production requirements. If your safety sign reads: “We Have Worked 1 Day(s) with Zero Accidents”, then maybe it’s time to review and improve your plant safety program. It’s everyone’s responsibility to…
AutomationDirect’s line of Stellar® soft starters now includes the SR55 series of solid-state soft starters to control three-phase AC induction motors. Designed to withstand up to 477 FLA (at 200-480 VAC), SR55 full-featured solid-state soft starters are available in three frame sizes and provide many advantages over electromechanical contactors. SR55 soft starters are fully digital, provide…
How are you keeping your operators’ hands, head and other body parts away from running machinery? Suitable mechanical guarding and guard switches are a good place to start—whether they are tongue interlock, non-contact, hinge interlock, cable pull or other types of safety switches. However, for improved protection of operator body parts from operating machine hazards,…
Those of us who have worked with, or around, electrical equipment have witnessed electrical arcs. At the very least, we’ve seen the sparks produced when a relay or contactor switches off. This is easily observed by watching a motor starter with open contacts. When the motor turns on,
We asked you all to submit a photo to show us why you’re in need of an HMI upgrade. It didn’t matter if you were planning to build a new project, trying to bring life to an old machine, or wanting a new HMI just to have it. We just said get creative. So we didn’t know…
Creating an accurate software simulation for a complex system can be difficult, but there are many reasons to do it. Creating simulations of automated equipment, processes, and robot sequences is a great way to validate controller programming, test hardware settings, and check HMI configurations—all without cycling the actual equipment. There can be many advantages to simulation,…
