Energy Storage and Signal Conditioning Performance

The GE IS200TVBAS2A IS200TVBAS2AAA stores enough energy for stable probe bias. Its six capacitors provide 1,980 µF of total capacitance. This storage filters out supply noise from the excitation voltage. Furthermore, each conditioning circuit provides adjustable gain for different probe sensitivities.

Role Within the Mark VI Protection System

You will typically find the GE IS200TVBAS2A IS200TVBAS2AAA mounted near the turbine bearing housing. It connects to the main rack via a shielded ribbon cable. Moreover, this board supports both standard and reverse-mount probe configurations. Its six channels monitor up to six vibration probes simultaneously.

Installation and Probe Wiring Guidelines

Use the GE IS200TVBAS2A IS200TVBAS2AAA as a direct replacement for older TVBA 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 four mounting screws and tighten all probe connections.
