Key Technical Specifications

This GE IS200VVIBH1C IS200VVIBH1CAC board operates from a 24V DC power supply. It monitors 8 vibration input channels for VME-based turbine systems. The unit measures 23 cm in length, 17 cm in width, and 4.5 cm in height. Its total weight reaches 0.75 kg without any packaging materials.

The GE IS200VVIBH1C IS200VVIBH1CAC includes 8 analog input channels for accelerometer signals. Additionally, it features one VME backplane connector for host interface. A single 6-pin terminal block connects the DC power input. The board contains 8 signal conditioners, 1 FPGA, 8 voltage regulators, 8 status LEDs, 24 resistors, and 18 capacitors.

GE IS200VVIBH1C IS200VVIBH1CAC stores energy using one electrolytic capacitor. This capacitor provides 100 µF at 35V rating for input filtering. Consequently, the board maintains stable readings during 20 millisecond power fluctuations. Therefore, vibration measurements remain accurate in noisy industrial environments.

Design and Integration

Both the GE IS200VVIBH1C and IS200VVIBH1CAC versions share identical vibration monitoring circuitry. These boards use four-layer PCB construction with guarded analog traces for noise rejection. Consequently, the GE IS200VVIBH1C IS200VVIBH1CAC operates reliably from -10°C to +55°C ambient temperature.

For installation, you need M3 screws for the four mounting holes. The board draws 200 mA typical current from the 24V DC supply. Each input channel includes software selectable gain and filtering. We recommend using shielded coaxial cables for all accelerometer connections.

Practical Application

This VME vibration monitor board connects accelerometer sensors to a VME-based turbine control system. It measures bearing and casing vibration in real time. The GE IS200VVIBH1C IS200VVIBH1CAC then routes conditioned signals to the host controller. Therefore, it enables predictive maintenance and vibration protection for GE turbine systems.
