This storage prevents false vibration readings from supply fluctuations. Furthermore, each amplifier provides adjustable gain for different probe sensitivities.

Role Within the Mark VI Protection System

You will typically find the GE IS200TVIBH2B IS200TVIBH2BAA in the turbine protection panel. It connects to up to four proximity probes or accelerometers. Moreover, this board supports both eddy current and seismic sensor types. Its conditioned outputs go directly to the vibration monitoring card.

Installation and Sensor Wiring Guidelines

Use the GE IS200TVIBH2B IS200TVIBH2BAA as a direct replacement for older TVIB revisions. Always verify the probe cable polarity before connecting to the 5-pin ports. This terminal board requires no external power supply for operation. It draws all necessary power from the backplane connector. Simply secure the board with its ejector tabs and tighten all sensor screws.
