Electromechanical Versus Solid-State Control Systems in Packaging and Material Handling: Case Studies

While this discussion is limited to two specific systems, the design considerations presented can be applied effectively in the selection of equipment for any type of control system. The use of solid-state controls for the Colgate-Palmolive interface system and electromechanical controls for the Kitchens of Sara Lee interface system was clearly indicated by differing design requirements. In many cases, however, the choice will not be so apparent, and it is the responsibility of the designer or user, in each instance, to weigh and determine the relative importance of design considerations.
