The GE IS200TVIBH2B IS200TVIBH2BBC terminates vibration sensor signals for monitoring systems. This board connects proximity probes and accelerometers to the main controller. It fits directly into GE Mark VIe and EX2100 protection racks. You will use this unit for reliable turbine vibration data acquisition.
Technical Specifications Overview
This vibration termination board features eight independent input channels for analog sensors. Each channel accepts signals from eddy current or piezoelectric transducers. The GE IS200TVIBH2B IS200TVIBH2BBC provides a built-in -24 V DC supply for proximity probes. A dedicated buffer circuit preserves signal integrity over long cable runs. Consequently, you obtain accurate vibration readings without field calibration drift.

Internal Components and Energy Storage
The GE IS200TVIBH2B IS200TVIBH2BBC contains one main PCBA with 126 discrete components. Key parts include eight instrumentation amplifiers and eight buffer op-amps. The board also holds four electrolytic capacitors storing 680 µF of energy. This storage smooths the -24 V supply for stable probe excitation. Moreover, a precision voltage reference maintains accurate signal scaling across all channels. Each channel includes a transient protection diode for surge immunity.
Physical Interfaces and Connectors
You will find one rear-facing 50-pin connector on this board. This connector links to the Mark VIe VME backplane for data transfer. Eight front-facing BNC jacks provide easy sensor connections. A separate 2-pin header supplies external -24 V monitoring access. Eight green LEDs indicate active signal presence on each channel. One red LED lights for any power supply fault condition. Six mounting holes secure the GE IS200TVIBH2B IS200TVIBH2BBC firmly to its mounting plate.
Installation and Operational Reliability
Install this vibration termination board inside a low-vibration control cabinet. Keep BNC cables away from high-voltage AC lines for noise reduction. The board performs signal conditioning without any software configuration. Therefore, you connect sensors and receive data immediately. This unit supports continuous monitoring in steam and gas turbine applications.
