  • Shielded Conduit Protects Against RFI/EMI

    Three kinds of shielding provide maximum choice

    Many applications require shielding effectiveness from RFI and EMI interference. Stray voltage, current, and high frequency noise can damage circuits, interrupt performance, and initiate potentially dangerous actions. Shielding reduces these potential problems. Shielded conduit, especially where flexibility is required, provides a significant solution for the engineer.

  • Business Information and the Cloud

    I've seen a lot of changes in business computing over the last three decades. Once upon a time, all you needed was a large enough closet to house a server or two. And, of course, some cable looms to keep your cabling neat and tidy.

    A rack system on the wall supported a few ethernet switches to handle incoming cables and route them to the servers. To keep things cool, an air conditioner was ducted into the space, ensuring the equipment wouldn't overheat.

  • Siemens Offers Advanced Panelboard Options

    Siemens has come out with a couple of newer advanced Panelboard options for contractors and building maintenance staff.

    The first is a Title 24-Compliant PS Lighting Panel intended to meet various disaggregation requirements, with CT provisions for metering segregated loads with P2 panels with up to 400-amp buses in a 20 inch x 7.75 inch Type 1 or NEMA 3R enclosure.

  • Data Center Products: More than Just Neat and Tidy

    In a previous article, I mentioned how data centers evolved from tiny spare closets to huge data-only facilities, often housed underground.

    There's no doubt that as the need for big data and other information increases, the data centers that gather and distribute this information will evolve as well. And, they're getting huge.

  • Testing the Mettle of Metalic and Non-Metallic PLC Enclosures

    At the heart of today’s automated manufacturing operations are programmable logic controllers (PLCs), which are miniaturized computers installed throughout a factory floor. These devices receive input from sensors throughout the line and use that data to issue commands to control machinery operations. Though PLCs are individually protected in rugged casing, they often are ganged together in enclosures specified according to application-specific needs.

  • Helping PLCs Keep Their Cool

    Programmable logic controllers (PLCs) are the ruggedized computers that run most automated manufacturing processes, from simple conveyor lines and pick-and-place operations, to more sophisticated machining and robotics applications. Though individual units are often quite small, PLCs are often installed in ganged enclosures and, like other types of computer equipment, they can produce a lot of heat. As a result, specifiers and contractors need to consider cooling options to protect against equipment overheating and failure.
