  • 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.

  • Pentair Offers Non-Metallic Trough Applications

    Contractors building raceway and running wires in corrosive or hazardous environments might opt for non-metallic trough. Examples include infrastructure work such as roads, bridges, tunnels or airports and commercial applications where chemical, dust or corrosion resistance is needed. Other markets include indoor manufacturing operations, water and wastewater applications. Salt-water or marine applications such as off-shore oil drilling are other applications, as is mining and large construction.

  • 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.

  • Power Quality, Part One – What Is It?

    "I have sensed a powerful disturbance in the force."

    Sorry about that! I just finished watching a "Star Wars" marathon. I don't know how many times I heard that phrase… often preceding some cataclysmic and universe-altering event.

  • Power Quality Part Two – Measurement and Control

    In Part One, we talked about power quality and some of the definitions outlined by the Institute of Electrical and Electronics Engineers (IEE). I hope you found that information useful.

    Now that you know some of the issues that power quality can present, the next steps are: measuring power quality, and controlling it.
