CNC routers use step and direction signals to control each stepper motors. In addition motor information (position, temperature, fault) gets transferred from stepper motors back to control unit. This must be done in star topology and a mix of proprietary interfaces. Simple open real-time Ethernet (SORTE) enables 4 µs cycle time on industrial Ethernet and replaces step/direction signal and motor feedback info into a single Ethernet cable that is also wired in line topology.
A common method to measure process parameters in plants is based on sound waves. This method is used in: level, flow and displacement field transmitters. It works based on measuring the time of flight (ToF) between when the pulse, generated by a piezo electric crystal, is sent and received back by the piezo.
This training helps to understand relevant parameter of a 4-20mA analog input module, such as surge protection, handling miss-wiring, broken wire detection, isolation or protection of the module against over-current at power and signal inputs.
Analog outputs in industrial automation come in a variety of configurations that each must deliver strong precision while passing stringent EMI /EMC certification tests. This session will address these systems and their challenges by explaining each configuration, and explaining example designs
Before we dive into specific application-based examples of noise and EMI mitigation, let's start with the basics. What is noise? What is EMI? What is ripple? How are they measured? What are some common approaches to limiting their effects? This section discusses these topics with a more conceptual approach to serve as a primer for the rest of the series.
Now that we understand the sources of EMI and noise in switching regulators, and some of the common approaches to mitigating each, let's take a closer look at real-world examples of reducing their effects. In this section we will examine the impacts of various mitigation techniques to help you decide which approach makes the most sense in your design. Techniques covered in this discussion include external component placement, filter options and design, frequency manipulation via spread spectrum or dithering, snubbers, boot resistors, and more.
Noise and EMI can be detrimental to sensitive analog signal chain circuitry. For this reason, many engineers automatically default to linear regulators. But, in doing so, they are essentially trading one problem (noise) for another (heat dissipation). In this section we will discuss what types of signal chain loads can be driven directly by a switching regulator to get low noise and EMI without sacrificing efficiency. We will also discuss when a linear regulator is absolutely needed to reach levels of noise not possible with a switcher.
Because of the potential havoc that interference can wreak in radio and safety critical systems, automotive electronics are subject to the most stringent EMI standards- the most common being CISPR25 Class-5. The materials below provide a discussion around the sources of EMI in an automotive environment and a comprehensive blueprint to understanding how to minimize it's effects.
The presentation addresses the design consideration of USB Type-C power delivery. USB Type-C is the new trend of Industrial, automotive and personal electronics devices. In the training, audience will be able to learn more about USB Type-C power delivery (PD) requirement and understand architecture of USB Type-C PD, AC/DC power source.
The presentation addresses the Precision DAC Architecture overview, DAC spec parameters and the theory of operation & Design example. All the information is importer for engineer when work on the system design.
Building automation system is a communication network infrastructure that manages the building service. This training will introduce the environmental sensor black diagram, key reference design and the solution for IC temperature sensor, power saving analog temperature sensor, digital temperature sensor … etc.
The training provides a very comprehensive introduction of the commonly-used interfaces including RS-485, RS-422, ProfiBus, RS-232, IO-Link, CAN and LIN. These interfaces are used in the application of Factory Automation and some other industrial applications. For the engineer who needs to deal with interface system design, this is a very useful training.
