Event Recorder
To enable more effective distribution, post fault analysis and troubleshooting, the Multilin DGCM provides an integrated event recorder and detailed diagnostic features. The event recorder offers:
• Storage for up to 1024 consecutive events
Trending and Data Logging
The Multilin DGCM provides a 200 channel RMS recorder for advanced disturbance diagnostic features.
The Multilin DGCM data logger helps in better understanding the analog channel behavior, by sampling at a selectable time interval rate of 1 to 60 minutes.
The Multilin DGCM event recorder enables users to analyze the sequence of events . Each event is stored with the event number, date, time and analog data of interest.
