Core Function: Dedicated acoustic monitoring termination board for Mark VIe turbine control system. It receives two‑wire signals from on‑site acoustic and vibration sensors, completes signal termination, noise filtering and buffer output. Transmits processed signals to rear‑stage signal processing unit for turbine casing acoustic monitoring and early mechanical fault diagnosis. Supports TMR triple‑modular redundant configuration, effectively suppresses high‑frequency electromagnetic interference and ensures reliable signal acquisition.

Product Details

The IS210SAMBH2AA (MRP688936) is acoustic‑vibration signal terminal board for GE Mark VIe Speedtronic turbine control system.

This plug‑in board is installed inside Mark VIe turbine control rack, equipped with high‑density terminal blocks for field acoustic sensor and vibration sensor wiring. It provides 18 groups of two‑wire input and buffered output channels, responsible for routing sensor acoustic‑vibration signals to subsequent processing boards. Built‑in passive EMI filter suppresses external high‑frequency noise, improves anti‑interference performance of measurement loop. It is mainly used for turbine casing acoustic monitoring, realizing early warning for mechanical looseness, component wear and abnormal impact faults.

Adopts conformal coating protection for circuit board, excellent anti‑vibration and anti‑interference performance, adapts to harsh electromagnetic environment of turbine hall in power plant. Compatible with TMR triple‑modular redundant safety control architecture of turbo‑generator unit.

It is important signal termination spare part for Mark VIe turbine control system, widely used in overhaul and renovation projects of gas‑steam turbine generating units.

It is important spare hardware for turbine acoustic‑vibration measuring loop debugging and defective IS210SAMBH2AA board replacement.
