IS200TVBAH2ACC IS200TVBAH2A VIBRATION INPUT TERMINAL BOARD
Product Description
IS200TVBAH2A is a Vibration Input Terminal Board and is part of the GE Speedtronic Mark VIe gas turbine control system. The PVIB / YVIB I/O pack uses the Vibration Input (TVBA) terminal board as a signal interface board. Seismic (velocity), Proximitors, Velomitors, and accelerometer-type probes can all directly connect with the TVBA. For each input signal, the terminal board offers electromagnetic interface (EMI) protection and signal suppression. To enable open circuit identification, signals are additionally coupled to a pull-up bias. Through a 37-pin connector, the signals are sent to the I/O packs.
IS200TVBAH2A Functional Description
- You can utilize the component for simplex or TMR applications. Three I/O packs are fanning the signal using TMR applications. The TVBA contains buffered outputs to additional connectors beyond the conventional 37-pin connection. This feature enables the Bently Nevada 3500 monitoring system to be powered via specific 9 and 25 pin connectors. This feature also includes a bayonet nut connection (BNC) connection for each channel to feed other third-party monitoring apparatus. Mark RKPS power supply are not used by VIe/VIeS control systems.
- There is no external source of -28 V electricity; power is acquired from sourced +28 V power supplies.
- The module features three detachable daughterboards to convert +28 to -28 as a result. All negative power used by the TVBA comes from these WNPS (negative power supply) boards.
The IS200TVBAH2A is a printed circuit board developed for General Electric’s Mark VIe Speedtronic Turbine Control System Series. This PCB can be more explicitly defined as a Vibration Input Terminal Board. This model PCB is considered a revised product; existing as a modified version of the original IS200TVCAH2 printed circuit board. The Mark VIe Series that this IS200TVBAH2A printed circuit board or PCB for short belongs to, as you have probably been able to guess based off of its full extended series name alone, has a specific set of applications in the management and control systems of popular and GE-compatible gas, steam, and even wind turbine automated drive assemblies. The current automated industrial market validity of this IS200TVBAH2A product’s greater Mark VIe Series is increased by this IS200TVBAH2A PCB’s Mark VIe Series’ status as one of the final-developed GE Mark product series to incorporate the patented Speedtronic control system technology into a range of its different offerings.

Product parameter
Manufacturer: General Electric
Country of Manufacture: United States (USA)
Series: Mark VI
Function: Terminal Board
The IS200TVBAH2A Vibration Input Terminal Board makes use of a series of unique and interesting hardware specifications. For starters, it is important to acknowledge that this model printed circuit board, as with any Mark VIe system PCB, does not use the traditionally-compatible RKPS power supply. Instead, power for the IS200TVBAH2A is acquired from several sources 28 V power supplies. No external source for this 28 V voltage is supplied, as the IS200TVBAH2A model must maintain the exact same functionality of the Mark VI TVIB board. Additional TVIB board likeness for the IS200TVBAH2A is supplied through the inclusion of three removable daughterboards; capable of converting +28 V voltage to -28 V voltage. All of the negative-voltage power supplied to the IS200TVBAH2A should be contained in these daughterboards. While the IS200TVBAH2A does boast some interesting functionality and functional components similar to that of the TVIB board; it differentiates itself through an additional series of component parts. The overall assembly of the IS200TVBAH2A Vibration Input Terminal Board includes:
- two terminal blocks
- 14 sensor inputs wired to the terminal blocks
- 24 terminals in total
- a shield termination attachment point
- a series of eleven plugs for Bently-Nevada data
- a 37-pin connector
- additional buffer outputs to enhance connections beyond the 37-pin
- and many more important components
Application field
Installation 14 sensor inputs that are wired directly to two I/O terminal blocks are accepted by the TVBA. Each block has 24 terminals that may accommodate wires up to #12 AWG and are secured with two screws. Each terminal block is close to a shield termination attachment point.
Input Channels 1 through 8:
- Support for Proximitors, Seismics, Accelerometers (only channel 1, 2, and 3), and Velomitors.
- Current-limited -24 V power supply per channel. JPxA jumper for configuring the open circuit check support and 3 mA constant current feed for Velomitors.
- JPxB jumper for configuring the JA1 and JB1 outputs for the Bently Nevada 3500 rack. JPxC jumper for configuring PR0xL as Open for true
Input Channels 9 through 12:
- Only Proximitors sensors are supported.
- Each channel has a current-limited -24 V power supply.
- Jumper setup is not allowed.
Input Channel 13:
- Proximitors or Keyphasor proximity sensors are supported on Input Channel 13.
- Each channel has a current-limited -24 V power supply, and jumper configurations are not allowed.
-28 V power supply board, WNPS:
- Changes +28 V from PVIB/YVIB to -28 V for the outputs’ current limits of -24 V.
- Independent +28 V inputs and a shared -28 V bus for all three WNPSs
- One WNPS per PVIB/YVIB
Operation
14 sensor connections are supported by the TVBA:
- Eight Positions or vibrations (ckts 1 through 8)
- Only four positions (ckts 9 through 12)
- One Keyphasor (reference probe) or location (ckts 13)
- A single Reference probe (Keyphasor)
