Description
Overview
The IS200TVIBH2B vibration terminal board is part of GE’s Mark VIe turbine control platform, designed to interface vibration and position sensors with the system’s protection and monitoring logic. It supports both permanent condition‑monitoring connections and temporary diagnostic access, making it a versatile component for turbine health assessment and protection.
Functional Architecture
The board provides two independent vibration channels and includes BNC connectors for portable analyzers, allowing technicians to perform field diagnostics without disturbing permanent wiring. It maintains continuous connections to Bently Nevada monitoring systems, ensuring uninterrupted data acquisition for radial vibration, axial position, eccentricity, and other critical parameters.
Sampling characteristics are optimized for turbine‑specific frequency ranges, enabling accurate detection of developing mechanical issues. The IS200TVIBH2B integrates directly with Mark VIe protection logic, supplying conditioned signals used for alarm generation and trip decisions.
Mechanical and Electrical Design
Built for demanding turbine environments, the board uses MIL‑spec connectors and a rugged mechanical layout. DIN‑rail mounting simplifies installation and service. Measurement accuracy is typically better than 1% of full scale, supporting precise vibration trending and fault identification.
LED indicators provide immediate visual confirmation of channel status, while 4–20 mA outputs allow integration with auxiliary monitoring systems. The design supports cyber‑secure communication pathways consistent with modern power plant requirements.
