Learn about serial and parallel data communication modes, errors, and flow controls used in connecting legacy and even some modern point-to-point network devices. Parallel transmission allows multiple bits to transmit simultaneously over multiple wires, enabling a device to send and receive data at high speed, while serial communication involves the transmission of bits one after … Read more
Ground fault circuit interrupters (GFCI) are commonly seen in residential wiring. They are important to understand, as they exist to protect both the users and the electrical systems used everyday. We see ground fault circuit interrupters, or GFCI outlets everywhere in residential wiring. Some breakers even have ground fault protection characteristics. However, even though grounding … Read more
Within an industrial setting, noise from EMI can create huge problems. For large load devices using many amps of current, small electrical noise may not be too critical. But when it comes to low-voltage and low-current communication wires, just a small amount of voltage finding its way onto a wire can corrupt data transmissions. Shielded … Read more
Whether working with measurement tools or process controllers, it is important to recognize faulty display values and the best ways to fix them. Electrical and electronic instrumentation is a critical part of the automation system, and the performance of attached equipment significantly depends on its satisfactory operation. Like other machine parts, instrumentation also malfunctions and … Read more
Recognizing the value of a multimeter is a great first step. It’s important to know why a meter may help to save time during design and troubleshooting, and therefore save money. Just as important is the next step of understanding the wide assortment of meters, and the unique situations in which each one may prove … Read more
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. Circuit breakers are overcurrent protection devices found in commercial, residential, industrial, and agricultural applications. In the manufacturing environment, these are most … Read more
We know what a circuit breaker is meant to do: stop the flow of electricity in case of a fault or failure. But just like fuses, breakers and overloads respond differently depending on the load. Circuit breakers and motor overloads are designed to open a circuit under dangerous overcurrent conditions. This is often less about … Read more
Protection against faults is crucial for any electrical system. This article examines various protective devices, highlighting their roles and best use cases to ensure system integrity and longevity. Overcurrent conditions from short circuits, power surges, and other anomalies can cause damage to sensitive components, leading to costly repairs and downtime. The absence of proper protective … Read more
Linear and switch-mode power supplies provide direct current to power control components and electrical devices. Learn about the differences between the two power supplies and which one is best for your control system. Power Supplies in Industry Alternating current (AC) power is created in a generator or alternator and continuously switches polarity as the generator … Read more
Two common methods exist for driving induction motors with VFDs – linear scalar control, which is often labeled as V/f, and vector, or field-oriented control, which can be a bit more complex to understand. Variable frequency drives are the industry-standard method of controlling 3-phase induction motors. The output of a VFD creates a DC pulse … Read more
