GE IS200TVBAH2AAA

Product Overview

GE IS200TVBAH2AAA is a dedicated and high-performance I/O processor module designed by General Electric for its advanced Mark VIe and Mark VIeS turbine and process control systems. The official name is "Turbine Vibration and Buffer Amplifier Interface". As one of the core components of the Mark VIe distributed I/O architecture, the TVBA card is not merely a simple signal conversion board; rather, it is an intelligent front-end processing unit.

Product Specifications and Parameters

The key specifications of IS200TVBAH2AAA are as follows

Product Series                GE Mark VIe / Mark VIeS I/O System

Module Type                  Turbine Vibration and Buffer Amplifier Interface Card

Model                            IS200TVBAH2AAA

Hardware Revision          H2A

Input Channel Count       4 independent buffer amplifier input channels

Input Signal Type           -24V DC buffer output

Input Voltage Range      -23.5V to -1.0V DC

A/D Converter               Independent 16-bit ADC per channel, ensuring high resolution and accuracy

Sampling Rate               Up to 10 kHz per channel, sufficient to capture high-frequency vibration events

Signal Isolation              Electrical isolation between channels and between channels and ground to prevent ground loop interference, improving system noise resistance

Power and Output Specifications

Sensor Excitation Power          Provides -24V DC ± 1% excitation power for each connected preamplifier

Power Current                       Each channel can provide a maximum of 30 mA current

Status Monitoring                   Continuously monitors the preamplifier power current and output voltage of each channel to detect open circuits, short circuits, or preamplifier failures

Communication and Processing

Communication Interface        Connected to the controller via the I/O backplane, using high-speed Ethernet for data exchange

On-board Processing              Built-in microprocessor, performing self-checks, signal conditioning, data packaging, etc., and uploading raw voltage values and diagnostic status to the controller. Note                The TVBA itself does not perform FFT or alarm calculations; these are performed by the controller

Physical and Environmental

Installation Method                 Installed in the Mark VIe Local I/O Pack, occupying a standard I/O slot. LEDs

Green LED OK                        Constantly on indicates that the module is working normally

Red LED FAULT                      Constantly on indicates that the module has detected an internal fault or communication interruption

4 yellow LEDs CH1-CH4          Indicate the status of each channel respectively

Operating temperature           -25°C to +70°C
