Are There Any Savings by Switching to Machine-Mount I/O?

We're contemplating a switch to machine-mount I/O from cabinet-mount I/O for some areas of our larger printing presses. We know that machine-mount I/O is more expensive, but we think we can make up some of the difference because we won’t have to design, purchase and install remote I/O cabinets. Are there any other savings from using machine-mount I/O as opposed to conventional cabinet-mount I/O? Are there any safety or other issues that we should be aware of before we make the switch?

  • <p>Having been personally involved in machinery mounted controls. I never recommend this very poor practice. Even on very low vibration or in a poor environment, it is a bad idea. The preconceived notion that it is saving money is far from the desired results. I will give an example of why to do it. The packager or manufacture of a plant or ship, like this as they can build and test a piece of machinery on the shop floor. The best way it to put all the controls and components in a separate control cabinet remote mounted sealed and on vibration mounts. You can mount things directly on machinery buy be sure to add spares of every component and the training to go with it to your maintenance team. Keep track of the personnel, so you know who is trained to maintain the machinery. The added cost of an external cabinet and the one -time cost is nothing to the long term cost or downtime. I always removed all critical controls off the engine or equipment and remote mounted with hose and flexible connections. Not only do you increase the operating life but make it a lot safer for the operating personnel. We even designed out operating cabinets with a shelf to hold tools, parts and many times a laptop for testing, setup and maintenance. </p>
