DeltaV™ M-series Sequence of Events Card

DeltaV

The DeltaV™ Sequence of Events Card provides a means of recording the events associated with a process upset by using highly accurate time stamps to determine the precise order in which they occurred. The Sequence of Events Card captures process-upset events close to the source for fast recording and provides increased resolution of timestamps for more accurate event sequencing.
