Functional Description

IS400TVBAH2BAA is a Vibration Terminal Board developed by GE. It is a part of the Mark VIe control system. Vibration Terminal Board plays a critical role as a signal interface board designed specifically for use with the Mark VIe I/O pack PVIB. TVBA serves as a direct interface for various types of vibration probes like seismic (velocity), Proximitors, Velomitors, and accelerometer-type probes. It ensures seamless connectivity and signal transmission between these probes and the Mark VIe system.

Features

  • Signal Suppression and EMI Protection: Each input signal is equipped with signal suppression and electromagnetic interface (EMI) protection mechanisms. These features safeguard against signal interference and ensure reliable operation even in challenging electromagnetic environments.
  • Open Circuit Detection: Signals are connected to a pull-up bias, enabling open circuit detection for enhanced system monitoring and fault detection capabilities.
  • Connectivity: Facilitates connectivity to the Mark VIe I/O packs through a 37-pin connector, enabling seamless integration into the overall system architecture. It supports both simplex and TMR applications, with TMR applications distributing signals to three I/O packs for redundancy and fault tolerance.
  • Buffered Outputs: In addition to the standard 37-pin connection, the TVBA includes buffered outputs to accommodate special 9 and 25 pin connectors, enabling integration with the Bently Nevada; 3500 monitoring system. Each channel also features a bayonet nut connection (BNC) to support connection to third-party monitoring equipment.
  • Power Supply: Unlike traditional systems utilizing the RKPS power supply, Mark VIe systems derive power from sourced +28V power supplies, eliminating the need for an external -28V source. To maintain functionality consistent with the Mark VI TVIB, the TVBA incorporates three removable daughterboards known as WNPS (negative power supply) to convert +28V to -28V. These daughterboards serve as the source for all negative power utilized by the TVBA, ensuring seamless compatibility and performance.

Power Supply

  • Number of Buffered Outputs: The power supply features a total of 14 buffered outputs, providing ample connectivity for various components within the system.
  • Amplitude Accuracy: The power supply ensures precise amplitude accuracy, with deviations kept within ±0.1 percent. This high level of accuracy contributes to stable and reliable performance in powering connected devices.
  • Amplitude Accuracy at DB Connectors with BNC Shorted: Even with the BNC connectors shorted, the power supply maintains its ±0.1 percent amplitude accuracy, ensuring consistent performance across different connection configurations.
  • Ability to Drive Load: The power supply exhibits robust capabilities in driving loads, with the ability to handle a minimum load of 1500 pF and a maximum load of 1000 pF. This ensures compatibility with a wide range of connected devices, accommodating diverse system configurations.
  • Overshoot Control: With overshoot limited to less than 10%, the power supply effectively manages transient responses during load changes, preventing excessive voltage spikes and ensuring stable operation of connected components. This feature enhances system reliability and protects against potential damage due to voltage fluctuations.

Frequently Asked Questions

What is IS400TVBAH2BAA?
It is a Vibration Terminal Board developed by GE under the Mark VIe series.

What is the function of Jumpers J1A through J8A?
Jumpers J1A through J8A are used to configure the biasing and voltage sources for different types of sensors connected to the terminal board. For seismic (S) inputs, they provide a high-impedance bias for open-circuit protection, while for proximity (P) or accelerometer (A) inputs, they provide a similar bias. Velomitor (V) inputs are provided with a constant current source.

What is the purpose of Jumpers J1B through J8B?
These jumpers allow for the selection of DC blocking capacitors for the buffered outputs (BN) corresponding to proximity (P), Velomitor (V), accelerometer (A), and seismic (S) inputs. They can be configured to bypass the capacitors for certain sensor types.
