GE DS3800NMEA1K1H
Product Name: GE DS3800NMEA1 Vibration Monitoring Module
Product Overview: The DS3800NMEA1 is a vibration monitoring module developed for the Mark VI series, part of the GE Speedtronic control system. It collects and processes vibration probe signals from DVIB and TVIB terminal boards, digitizes the analog signals, and transmits them via the VME bus to the controller for equipment data monitoring and closed-loop feedback control. The DS3800NMEA1K1H is a variant of this module with specific revision codes.
