Part 1 takes a look at circuit grounding and its importance to you, as well as the US AC power system and its use of earth ground.
Part 2 examines our use of ground as protection, and how ground fault circuit interrupter devices operate to protect us from severe shock.
Part 3 examines the role of ground as a voltage stabilizer and transient limiter, along with tips on improving safety and signal integrity.
AcroPack™ Series of I/O mezzanine modules and carriers provide a cost-effective solution for a modular approach to system assembly enabling application specific customization. The innovative PCIe-based AcroPack Series of general purpose I/O modules for embedded computing applications are an extended version of the mPCIe specification and feature a 100-pin connector to handle the I/O. The modules plug into connectors on AcroPack carriers to add analog or digital input and output or communication in any combination for embedded applications running on Linux, Windows, or VxWorks operating systems. http://ow.ly/b2yk3008f7L
Very often the simple task of choosing an Isolator requires more than just comparing the number of channels and the cost per point. To help you with this exercise, here are a few concepts to know when specifying a 4-20 mA Isolator. #appnote
Our product line encompasses process instrumentation such as signal conditioning, isolators, transmitters, Ethernet and remote I/O. For real-time control systems, we offer high-performance analog, digital, and serial I/O bus boards, single board computers, and rugged small form factor systems.
Today, Acromag's product line encompasses a wide variety of I/O devices for manufacturing, military, scientific, public utility, and transportation applications. For process instrumentation, Acromag's signal conditioning line features more than 100 transmitters, isolators, alarms, and computation modules. If networked I/O is required, Acromag offers analog and discrete I/O modules for Ethernet, Modbus, and Profibus. For real-time control systems, Acromag provides a full line of high-performance analog, digital I/O and serial I/O bus boards for VMEbus, PCI, and CompactPCI® computer systems including IndustryPack® and PMC mezzanine modules.
Experience makes the difference. Acromag's years of experience in designing industrial I/O have given us a clear understanding of the problems associated with industrial measurement and control. Solutions to ground loops, RFI/EMI noise, and temperature drift are designed into every product to assure precise operation in hostile environments. Many products are available with agency approvals such as UL, cUL, FM, CSA, CE, ATEX, and others.
In addition to the over 3800 products available for shipment, Acromag has 50 years' experience modifying units and producing custom products. Once a modification is defined, Acromag enters it into our documentation system and it becomes available as a standard product. This means that it can be re-ordered at any time in the future simply by using the assigned model number.
You will find that Acromag products routinely out perform their listed specifications. Printed specifications reflect minimum performance standards that every product must meet or exceed before shipment. These conservative specifications guarantee a repeatable level of performance for all applications.
Strict quality control measures further assure you of the finest product. State of the art manufacturing and test equipment keeps Acromag's products the best in the world. Extensive burn-in procedures and demanding test requirements are among the strict quality control measures used to maintain the high levels of reliability that Acromag customers have come to expect. Over the last several years, Acromag has incorporated the latest techniques of statistical quality management to assure that we maintain and constantly improve our product quality.
Doing business with Acromag is easy. A global network of sales representatives and distributors gives you local access to friendly, highly-trained control professionals that can help you select the right products for your needs. Product information and online ordering are also available on our website . Customer-driven service programs include fast, on-time delivery (24-hour shipments on many products), extended warranties (up to 7 years), and convenient credit card ordering. Technical support is available from a team of experienced application engineers to help you find the best solution or to troubleshoot your system.
