Much of this process was discussed in a previous post.
Prior to drawing the schematics preliminary steps such as system concepting and creating an I/O list must be done. It also allows the designer to determine how many terminal blocks and other power and signal distribution devices will be needed. This accomplishes several things it ensures that all major devices are accounted for (controller, disconnect and power distribution devices, power supplies, ethernet switches and fuses/circuit breakers, VFDs/motor starters/servo drives and controllers, etc.). The first step in laying out an enclosure is to complete the electrical design schematics. voltage levels) into different enclosure bays, but when you only have one enclosure to put all of your stuff in you have to be careful about where you locate components. Many larger enclosures allow the designer to separate similar components (i.e.
I am using the above picture because it contains a variety of different kinds of components in the same enclosure. Doug asked me to cover a little more on the panel design process. I had planned on writing a bit about my meeting with the publisher last week, but I received a comment on a post from about a year and a half ago on Controls Specifications.
