GE IS200TVIBH2BCC Vibration Input Terminal Board Product Description

Overview

GE IS200TVIBH2BCC is a TVIB vibration termination board for the GE Mark VI Speedtronic turbine control system. This GE vibration input terminal board serves as the front‑end signal interface between vibration transducers and the matching VVIB vibration processor board. The GE IS200TVIBH2BCC vibration input terminal board integrates terminal blocks and BNC connectors, supporting connection of eddy current probes and accelerometers for rotating machinery condition monitoring. As a conformal‑coated GE turbine control spare board, IS200TVIBH2BCC is designed for rack mounting inside turbine control cabinets, widely used for new unit configuration, system retrofit and spare‑part replacement of Mark VI vibration monitoring loops.

Features

GE IS200TVIBH2BCC vibration input terminal board provides dedicated termination channels for high‑frequency dynamic vibration signals. This GE vibration input terminal board is equipped with BNC test ports, allowing technicians to access vibration signals with portable analyzers for on‑site predictive maintenance and signal verification. GE IS200TVIBH2BCC vibration input terminal board routes conditioned vibration signals to the backplane for transfer to the VVIB processing card for demodulation and calculation. The GE IS200TVIBH2BCC vibration input terminal board uses conformal coating to resist moisture, dust and mild corrosive contaminants in turbine room environments. This GE vibration input terminal board adopts standard Mark VI rack form factor, and supports hot rack replacement procedures following turbine control safety lockout rules.

Principle

GE IS200TVIBH2BCC vibration input terminal board receives raw dynamic vibration signals from field proximity probes and accelerometers. It provides stable signal termination, filtering and signal splitting: one path goes to the VVIB processor board through the rack backplane for continuous vibration amplitude and frequency calculation and unit protection logic; the BNC tap path provides accessible signal points for offline vibration measurement and troubleshooting. The VVIB board processes the data and sends vibration alarms and values to the Mark VI control core for machine protection and HMI display.

Applications

GE IS200TVIBH2BCC vibration input terminal board is mainly deployed on gas turbine, steam turbine and large compressor control skids using GE Mark VI control systems. This GE vibration input terminal board monitors shaft vibration and casing vibration of rotating equipment to trigger machine protection trips when vibration exceeds set limits. IS200TVIBH2BCC fits power plant turbine control cabinet maintenance, vibration channel expansion and replacement of legacy TVIB termination boards. It is critical hardware for machinery protection and predictive maintenance in power generation and heavy‑duty rotating equipment.

Installation & Maintenance Notes

Follow official GE Speedtronic turbine control manuals while installing GE IS200TVIBH2BCC vibration input terminal board. Execute proper lockout and turbine safety isolation before rack work, as vibration channels are linked to machine protection trips. Verify transducer wiring polarity and BNC cable integrity; poor termination will cause vibration signal drift or false alarms. Inspect conformal coating, connector tightness and terminal screw torque periodically, especially in high‑temperature turbine cabinet environments. Confirm exact part number IS200TVIBH2BCC during spare‑part swap‑out to guarantee form factor, channel layout and compatibility with existing VVIB and Mark VI rack configuration. Back up vibration protection setpoints before card replacement.
