A graphic terminal remains an invaluable asset within most automated systems. It gives operators a practical way to see what a machine is doing, respond to alarms, adjust process values, and keep production moving without needing to dig through the control cabinet every time something changes. Of course, the effectiveness of the terminal varies depending on factors such as screen size, graphic design, responsiveness, and so on. Because of this, it can get a bit overwhelming trying to spec the perfect HMI for your setup. Today, we’re here to narrow down your search with two popular offerings on the market: The Mitsubishi GOT2000 series and the Allen-Bradley PanelView 5500 series. Both of which are built for a serious industrial environment, yet lean into their own strengths that we will go over to help you make a more informed decision. Before diving into the comparisons, it’s best to go over what each HMI’s family is trying to accomplish. While the Mitsubishi GOT2000 and the...
The PowerFlex product family from Rockwell Automation spans one of the broadest drive portfolios in industrial automation. Engineering the right selection from within that portfolio requires understanding precisely where Rockwell draws the line between its compact and full-size (architecture-class) drive categories, and what technical capabilities exist on each side of that line. PowerFlex drives are broadly categorized into compact-class and architecture-class: compact drives are smaller, cost-effective units for simpler applications, while architecture-class drives are high-performance, feature-rich units for demanding industrial requirements. Here, we will discuss some parameters for comparing the two types of drives. Source PowerFlex 755 Drives Here Rockwell Automation organizes the PowerFlex family into three tiers: compact (component-class), standard, and architecture-class. The compact tier encompasses the PowerFlex 4 , 40 , 523 , 525 , and 527 series. The architecture-class...
An AC drive is basically a device that lets you control how fast and how hard an AC motor runs. It does so by changing the frequency and voltage of the power supplied to the motor. And knowing the difference between a general-purpose AC Drive and a high-performance AC Drive really matters if you’re into modern industrial automation. General-purpose VFDs are widely used because they handle most industrial tasks. But there are times when you need something more powerful and precise; that’s where high-performance drives step in. If you’re an engineer or have to make purchasing decisions, you need to know how these two stack up before you spend a dime. Shop for Allen-Bradley PowerFlex 525 Drives Here A general-purpose AC Drive is designed to suit a wide range of settings, including factories, businesses, and full-scale industrial environments. They’re flexible, so people tend to use them almost everywhere. Maybe you work somewhere that needs a motor control system that’s ready to scale up...
