How to Add Protection when Switching Inductive Loads – 8501088
The importance of adding protection to the load terminals in inductive load switching: a review of important inductor behaviors. Acromag manufactures products that are often used to switch inductive loads. For example, our digital outputs and alarm relays commonly drive inductive loads that include motor windings, solenoids, interposing relay coils, physical inductors, and even the…
What are PMC and XMC Modular I/O Standards? – 8401066
PMC and XMC Modular I/O – Established Standards in High Performance Systems The IEEE standard for PCI Mezzanine Cards (PMCs) initiated the first successful approach to truly modular I/O devices. Subsequent development has presented system integrators with the XMC modules, introducing support for switched interconnect protocols, adding contacts serial lanes for high-speed data transfer, and providing better…
What is the 250T Two-wire RTD Transmitter Failsafe Hook-Up Approach? – 8401068
Two-wire Transmitters and Their “Hook-up” to Achieve a Failsafe Configuration The attached analysis references Acromag’s 250T series RTD (100 ohm platinum) This type of hook-up is typically not used because the effects of lead-wire resistance inaccuracies are additive to the RTD measurement. However, when addressing the problem of FAILSAFE, this configuration offers the most predictable…
Speed Considerations for A/D Converters – 8401067
In this article, we will consider the basic conversion methods that are commonly implemented on commercially available boards and how these methods affect the throughput and accuracy of the data. Some Important Terms Resolution – The number of discrete values that a converter can produce over the range of analog values. A 12-bit A/D converter…
Inside a Multiple Channel Analog to Digital Converter – 8400953
Inside a Multiple Channel Analog to Digital Converter We will look at a common technique to implement A/D conversion in a Commercial Off-The-Shelf (COTS) board. The information is helpful in determining how to wire a system with multiple A/D sources. Acromag offers several A/D converters, including mPCIe-based Acropacks AP323 and AP341 and multi-function XMC module…
How Building A/D Applications from a Simple Base Can Minimize Problems Downstream – 8400531
Building A/D Applications from a Simple Base Can Minimize Problems Downstream Converting analog signals to a digital stream is easy, but great care is needed to ensure a clean signal A common task of real-time systems is to extract information from the real world in a form that can be manipulated by a computer to…
How do FPGA Modules Drive Real-Time Applications? – 8400530
FPGA Modules with an Integrated Processor Drive Real-Time Applications Engineers developing DSP and high speed logic applications are now well-aware that FPGA modules can help them create an integrated, sophisticated solution. The availability of commercial off-the-shelf (COTS) FPGA boards can make these solutions viable and do so in reduced development times. Today, with systems architected…
