Abstract
A modular overload relay provides a low cost analog base unit performing overload detection functions and one or more add-on units communicating with the base unit through an electric conductor on a side of the base unit to which the add-on module may be attached. The add-on units augment the circuitry of the base unit through additional analog or microprocessor-based circuitry communicating with various points within the analog circuitry of the base unit.
