Dynamometer Monitoring System (DMS)

Cell Interface Assistant III

The Dynamometer Monitoring System (DMS) provides the test cell operator with a user-friendly interface to a fixed set of test cell functions. The DMS includes a single, rack mountable, User Interface (UI) and hardware connection box. The UI includes a confi gurable touchscreen for virtual button control and visual indicators for items such as warnings, alarms, and function status.

The core function of the DMS package is to monitor discrete digital (on / off) and analog feedback for an AC dynamometer. It operates completely independent of any test automation software; therefore, providing protection for the test system regardless of operation mode.
