Application Fields
The IS200TVBAS1ABB is the primary interface for mechanical health monitoring in turbine systems. Its key applications include:
- Gas and Steam Turbine Vibration Monitoring: Tracking shaft vibration and bearing health.
- Proximity Probe Interfacing: Connecting Bently Nevada or similar displacement sensors.
- Seismic and Accelerometer Data Acquisition: Measuring casing vibration and structural integrity.
- Keyphasor Processing: Providing phase reference and speed data for rotating machinery.
- Industrial Power Plant Protection: Triggering emergency trips based on excessive vibration levels.
Product Instructions
- Installation: Mount the TVBA board in the designated termination cabinet. Use the 37-pin J-cables to connect the board to the VVIB (Vibration Processor) cards in the Mark VI VME rack.
- Wiring: Field sensors should be wired to the terminal blocks. Use high-quality shielded cables for all vibration signals to prevent EMI/RFI interference, which can cause false vibration alarms.
- Jumper Configuration: Depending on the sensor type (e.g., -24V DC Proximity vs. Passive Seismic), verify the onboard jumpers or hardware settings to ensure the correct power is supplied to the field device.
- Commissioning: Use the GE Toolbox software to calibrate the scale factors (e.g., 200 mV/mil) for each channel. Ensure the Keyphasor input is correctly mapped if phase-angle data is required.
Product Q&A
Q: Can the IS200TVBAS1ABB be used with Bently Nevada 3500 sensors? A: Yes, it is designed to interface with standard proximity probes and transducers, including those from the Bently Nevada line, provided the wiring and voltage requirements are matched.
Q: How does the TVBA support TMR (Triple Modular Redundancy)? A: In a TMR system, the signal from the terminal board is split and sent to three separate VVIB processor boards (R, S, and T). This allows the Mark VI to vote on the vibration data for high-reliability protection.
Q: What is the significance of the “S1ABB” suffix? A: “S1” typically denotes the group/style of the board, while “ABB” refers to the specific hardware revision. It is vital to match this revision in the system configuration to ensure diagnostic compatibility.
Q: Does this board provide the -24V DC power required for proximity probes? A: Yes, the TVBA board facilitates the distribution of transducer power (usually -24V) to the field sensors through its integrated circuitry and the connected power supplies.
