Description
1. Product Title
GE IS230TVBAH2A – Mark VIe Vibration Terminal Board
2. Product Overview
The GE IS230TVBAH2A is a specialized Vibration Terminal Board designed for the Mark VIe Distributed Control System (DCS). This module serves as the primary physical interface for vibration and proximity probes used in monitoring rotating machinery, such as gas and steam turbines. The IS230TVBAH2A is engineered to receive low-level signals from seismic transducers, accelerometers, and Proximitor® sensors, providing the necessary termination and signal conditioning before the data is processed by the associated I/O packs (typically the PVIB).
By facilitating high-accuracy vibration measurement, this board is instrumental in identifying mechanical imbalances, bearing wear, and shaft misalignment. Its robust design ensures that critical protection data is delivered with minimal interference, addressing the stringent safety and reliability requirements of modern power generation and heavy industrial facilities.
