Product Details
The IS200SAMBH1ABA (MRP681847) is acoustic monitoring terminal board for GE Mark VI Speedtronic turbine control system.
This board is installed inside Mark VI turbine control rack, equipped with high‑density terminal blocks for field acoustic and vibration sensor wiring. It provides 18 two‑wire signal input channels and 18 buffered output channels, transfers sensor acoustic‑vibration signals to subsequent signal processing boards. Built‑in passive EMI filter suppresses external high‑frequency noise interference, effectively improves anti‑interference capability of acoustic measuring loop. It is used for turbine casing acoustic monitoring, realizing early warning of component wear, looseness and abnormal impact faults.
Conformal coated circuit board enhances anti‑vibration and anti‑interference performance, adapts to harsh electromagnetic environment of power‑plant turbine hall. It supports TMR triple‑modular redundant configuration for turbine safety control system.
It belongs to key signal terminal spare‑part for Mark VI 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 IS200SAMBH1ABA board replacement.
