Abstract

An operator interface panel assembly is used with a programmable logic controller. Through the use of a printed wired circuit board, a wide variety of input and output components that must be accessible to an operator can be assembled by the user at the location of the installation rather than at the point of manufacture. The assembly can be easily reconfigured without costly rewiring of the installation. The same switch or pilot light position can accommodate a variety of one and two pole switches without hardware modification.
