A Better Fit: Comparing Electrical Systems vs. Pneumatic Systems

A Better Fit: Comparing Electrical Systems vs. Pneumatic Systems

Knowing what kind of control system to use: that’s a question that must be answered before setting up the factory floor. Why would someone choose pneumatic over electrical controls?


How Do You ‘Megger’ a Motor? Understanding Motor Insulation Resistance

How Do You ‘Megger’ a Motor? Understanding Motor Insulation Resistance

Within motors, two very different types of resistance are evident. The resistance of the windings is measured with a normal multimeter. But what is insulation resistance, and how is it measured?


Electrical Drawings, Schematics, and Wiring Diagrams: How to Read Them

Electrical Drawings, Schematics, and Wiring Diagrams: How to Read Them

In order to trace control system problems to the core, the ability to read and interpret various resources, from facility-level diagrams to machine-level wiring layouts, is critical.


What is a Soft Start? Reducing Start-up Load on Motor Circuits

What is a Soft Start? Reducing Start-up Load on Motor Circuits

Controlling the startup of a motor not only reduces the wear on the motor, but eases the burden on the electrical supply, reducing infrastructure demands and the running cost of industrial loads.


Data Flow Tutorial With Mage.ai | Part 6: Refined Data Presentation

Data Flow Tutorial With Mage.ai | Part 6: Refined Data Presentation

We conclude the data flow project with the step of developing a business intelligence dashboard to present machine data, at a reliable schedule, to a leadership or maintenance team.


Star-Delta Wiring for Reduced Voltage Starting of 3-Phase Motors

Star-Delta Wiring for Reduced Voltage Starting of 3-Phase Motors

Digital controls like VFDs and soft starts have advantages by elongating start time, but simple strategies for starting motors with a reduced current draw, like star-delta (or wye-delta) are common.


PLC Naming Conventions: How Should I Write My Tag Labels?

PLC Naming Conventions: How Should I Write My Tag Labels?

It’s important to consider your PLC tag naming convention when using different styles. Learn when and why you might even use more than one, depending on the circumstances and scope of your project.


What is a Circuit Breaker?

What is a Circuit Breaker?

We depend on circuit breakers all the time, even when you have a day off or work from home. These overcurrent protection devices keep machines running safely, reducing the risk of fires and arcing.


Understanding the 17xx | Your Rockwell/Allen-Bradley Hardware Encyclopedia

Understanding the 17xx | Your Rockwell/Allen-Bradley Hardware Encyclopedia

Rockwell Automation’s Allen-Bradley control hardware catalog has long included many series that start with 17xx, but what are these lineups, and what function do they serve?


What is a Variable Frequency Drive (VFD)?

What is a Variable Frequency Drive (VFD)?

When we need to change the speed of an industrial motor, whether to control a process or save energy costs, we turn to the variable frequency drive, better known simply as a VFD.


Strain Gauges: Real-World Considerations and Typical Applications

Strain Gauges: Real-World Considerations and Typical Applications

In this article, we will explore real-world considerations for strain gauge performance and typical applications. We’ll be talking about foil and wire strain gauges, but ignoring semiconductors.


Data Flow Tutorial With Mage.ai | Part 4: PostgreSQL Database

Data Flow Tutorial With Mage.ai | Part 4: PostgreSQL Database

To transfer data from a local spreadsheet to a database to create visual dashboards, we must now define the outbound integration to the PostgreSQL database through the mage.ai editor.


Info Byte: What Do NC and NO Mean?

Info Byte: What Do NC and NO Mean?

Some terminology, like 'normally open' and 'normally closed' switch contacts, is common throughout industry but can still be confusing, misleading, or even hazardous if not properly understood.


Data Flow Tutorial With Mage.ai | Part 3: Connecting to Google Sheets

Data Flow Tutorial With Mage.ai | Part 3: Connecting to Google Sheets

In this article, we will explore the inbound integration to the mage.ai pipeline, connecting to the spreadsheet data source using the Google Sheets API through a JSON credentials file.


Data Flow Tutorial With Mage.ai | Part 2: Initializing the Software

Data Flow Tutorial With Mage.ai | Part 2: Initializing the Software

Data pipelines are software services that progress the data from source to storage, hopefully without too much programming complexity. In this article, we begin by initializing the mage.ai software.


Identifying and Troubleshooting Pressure Changes in Fluid Systems

Identifying and Troubleshooting Pressure Changes in Fluid Systems

Pressures are always rising and falling in fluid systems. Sometimes the changes are extreme and lead to damage. What causes problematic pressure changes, and how can you trace them to their source?


Troubleshooting PLCs: Recognizing Visual Status Indicators and LEDs

Troubleshooting PLCs: Recognizing Visual Status Indicators and LEDs

Machine downtime can be very stressful for everybody involved. Next time you face a challenging system failure, try some of these LED troubleshooting techniques to reduce stress.
