Abstract: A Digital Programmable Motor Overload Protector includes a base module and a detachable, removable user interface module interfaced through a serial communications link. The base module provides motor overload analysis through a programmable Digital Signal Processor (DSP) which digitizes real time motor operating conditions, comparing stored user trip and alarm levels against these conditions, communicating the results to the detachable user interface and a multi-drop communications link using the industry standard MODBUS RTU protocol to a facility's automation system. Motor operating conditions, user settings, override conditions, pass events, and resettable parameters are available through the password protected removable user interface module or the multi-drop communications interface.

Abstract: The specification and drawings describe and show one embodiment of the present invention in the form of an umbilical cable connector, including a multi-pin plug connector at one end of a multi-wire insulated cable and a multi-socket connector at the other end. The invention can be used for remote control of various electronic and electrical components using programmable controllers. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.
