Logic uponwhich individual features are designed is fixed, and all other logic, from contact input signals through elements orcombinations of elements to contact outputs, is variable. The user has complete control of all variable logic throughFlexLogic. In general, the system receives analog and digital inputs that it uses to produce analog and digital outputs. Thefigure shows major subsystems of a generic UR-series relay involved in this process.
