Info Byte: The Mystery of Ice Cube Relays–Coil Polarity

Info Byte: The Mystery of Ice Cube Relays–Coil Polarity

Relay and other coil devices pose a few confusing questions: How can the relay still work if you connect a DC supply in reverse? How can an alternating voltage attract and hold the load consistently?


Why is 4-20 mA Current Used for Industrial Analog Sensors?

Why is 4-20 mA Current Used for Industrial Analog Sensors?

Industrial analog sensor devices primarily use 0-10 volt or 4-20 milliamp. For those mA signals, learn the reasons for why the lower and upper limit standards were determined as 4 mA and 20 mA.


Industrial Control Panel Design Standards and Best Practices

Industrial Control Panel Design Standards and Best Practices

Industrial control panels are at the heart of control systems. Learn about the standards and regulations that dictate industrial control panel design for safety and efficiency, including NFPA 70, UL 60947-4-1, and NFPA 79. 


 PLC Program Commands: Arrays and Pointers

PLC Program Commands: Arrays and Pointers

The ability to utilize an array effectively is a fundamental skill in becoming a PLC programmer, but it can also be very complex and difficult to master. Let’s do a run-down of arrays and some of their complexities!


3-phase Motor Types: Synchronous and Induction Motors

3-phase Motor Types: Synchronous and Induction Motors

In this article, we will take a look at the differences between synchronous and induction motors, as well as the two types of induction motors: squirrel cage and wound rotor.


Preventing Failures in High-Temperature Manufacturing Processes

Preventing Failures in High-Temperature Manufacturing Processes

Any machine can become a source of elevated temperature, even under regular operation. We cannot assume that temperature problems occur only based on climate conditions, and mitigation steps must be employed.


I/O Module Debate: Transistor vs. Relay Output?

I/O Module Debate: Transistor vs. Relay Output?

When selecting the right module for the right load, be sure to understand how the load resistance will affect the voltage and current of the output module terminals.


Recreating PLC Ladder Logic in an Arduino C/C++ IDE

Recreating PLC Ladder Logic in an Arduino C/C++ IDE

​​​​​​​Arduinos have been a staple in the community of makers, students, and project innovators for many years. For many using Arduino’s IDE, there can be difficulties in translating between PLC ladder rungs and text programming.


What is Firmware, and Why is PLC Firmware Important?

What is Firmware, and Why is PLC Firmware Important?

Inside a controller, code is interpreted into the binary signals that influence input and output signals, flags and registers, and even the communication of network signals. This is the job of firmware.


Interrupting Dangerous Current Flow: Fuses vs. Circuit Breakers

Interrupting Dangerous Current Flow: Fuses vs. Circuit Breakers

Fuses and breakers are some of the most common safeguards to prevent electrical shock and fires. Learn about these two pieces of industrial equipment and the difference between slow blow and quick blow responses.


How to Program a Robot: Industrial Robotic Arm Coding Basics

How to Program a Robot: Industrial Robotic Arm Coding Basics

The world of manufacturing is filled with robots, but beginners are still always faced with key questions, starting with perhaps the most basic: how do you program industrial robots?


Understanding Centralization vs Decentralization of PLCs

Understanding Centralization vs Decentralization of PLCs

Centralized control systems are often seen as outdated compared to decentralized systems; however, both have their advantages and disadvantages when it comes to choosing which one to use in manufacturing.
