IS200TVBAH2A

About the IS200TVBAH2A

• The IS200TVBAH2A is a printed circuit board (PCB) developed by General Electric.
• It is a Vibration Input Terminal Board within the Mark VIe Speedtronic Turbine Control System Series.
• This model is a revised version of the original IS200TVCAH2 PCB.
• Often referred to by its acronym TVBA.

Applications and Significance

• Specific applications in the management and control systems of GE-compatible gas, steam, and wind turbine automated drive assemblies.
• Its series (Mark VIe) is one of the final GE Mark product series to incorporate the patented Speedtronic control system technology.

Hardware Specifications and Functionality

• Power Supply: Does not use the traditional RKPS power supply. Instead, power is acquired from several 28 V power supplies (no external source supplied, must maintain TVIB board functionality).
• Negative Voltage: Includes three removable daughterboards capable of converting +28 V voltage to -28 V voltage. All negative-voltage power should be contained within these daughterboards.
• Interfacing: Provides direct interfacing for multiple types of probes.
• Signal Protection: Provides signal suppression and EMI protection for each individual input signal.
• Overall Assembly Components:
  • Two terminal blocks.
  • 14 sensor inputs wired to the terminal blocks.
  • 24 terminals in total.
  • A shield termination attachment point.
  • Eleven plugs for Bently-Nevada data.
  • A 37-pin connector.
  • Additional buffer outputs (beyond the 37-pin connector).
  • Many other important components.
• Coating: Features a conformal-style PCB coating, which is thinner but provides a more thorough and complete layer of protection than normal-style coating.

Product Revision Information

• Revised Model: Indicated by the "H2A" in the part number.
• Revision Type: Classified as a functional revision, enhancing overall efficiency and functionality.
• "H2A" Breakdown: Concurrently indicates a conformally-coated PCB, a group 2 series grouping, and a functional revision rated at an "A" grade.
