The GE IS210DVIBH1BA is a Vibration Terminal Board Assembly for the Mark VIe series of GE’s Speedtronic Gas Turbine Control Systems. The “DVIB” in the part number stands for DIN-rail VIBration. This board provides the physical interface for connecting various vibration and position sensors to the control system.
Key Features and Functionality
The IS210DVIBH1BA is crucial for monitoring the mechanical health of a gas turbine. Its main functions include:
- Vibration Sensor Interface: The board provides the physical terminal blocks for connecting vibration and proximity probes. It is designed to interface with sensors like accelerometers and proximity probes that measure shaft vibration, displacement, and axial position.
- Signal Conditioning: The terminal board includes circuitry for signal conditioning, which is essential for handling the high-frequency and low-amplitude signals from vibration sensors. This circuitry may include filters and signal converters to ensure the integrity of the data before it is sent to the main I/O pack for processing.
- DIN-Rail Mounting: The board’s design allows it to be mounted on a standard DIN rail, which is a common and efficient method for organizing and installing control system components in a cabinet.
- Redundancy Support: This board is typically used in redundant configurations to enhance system reliability. In a TMR (Triple Modular Redundancy) system, three separate DVIB boards can be used with redundant I/O packs to ensure that critical vibration data is always available, even in the event of a single component failure.
- Application: This board is used in safety-critical applications to monitor turbine and generator vibrations. High vibration levels can indicate a variety of mechanical issues, and the system can be configured to trigger alarms or even a trip if levels exceed a safe threshold.
