GE IS215VAMBH1A VME Processor Board for Mark VI Control System
Product Overview
The GE IS215VAMBH1A is a VME‑bus acoustic monitoring processor board built exclusively for the GE Mark VI Speedtronic turbine control platform. IS215VAMBH1A performs high‑speed dynamic acoustic signal acquisition, filtering and real‑time spectrum analysis for heavy‑duty gas and steam turbines. As a core diagnostic component inside Mark VI control racks, this VME processor board captures combustion dynamics signals, detects combustion instability, and sends alarm triggers to the main turbine controller to protect turbine hot‑gas path components from unexpected damage.
IS215VAMBH1A works paired with IS200TAMB‑H1A daughter terminal boards to realize full 18‑channel differential acoustic monitoring, widely deployed on Frame 6, Frame 7, Frame 9 gas turbine units in power generation, oil & gas and petrochemical plants. It fits standard 6U VME rack slots and gets power supplied from the Mark VI backplane bus for simple cabinet integration.
Key Features
- 18‑channel differential acoustic input with 8x oversampling sampling for high‑fidelity dynamic pressure signal capture
- FPGA‑based onboard signal pre‑processing: FIR digital filtering, open‑wire detection, real‑time RMS & peak amplitude calculation
- Native VME bus interface for seamless communication with Mark VI main processor inside TMR redundant control architecture
- Configurable alarm threshold for combustion oscillation; supports event‑triggered data snapshot for post‑fault diagnosis
- Wide operating temperature 0℃ ~ +60℃, built for harsh industrial cabinet environment of power plant site
- High channel‑to‑backplane isolation rating to suppress field noise interference from turbine sensors
- Support charge‑mode acoustic sensors, compatible with mainstream vibration & dynamic pressure sensor brands
Standard 6U VME form factor, direct drop‑in replacement for legacy Mark VI control rack maintenance
