Product Description
Product: DS200AAHAH2A – GE Mark V AAHA Gen2 ARCNET Hub Communication Board
GE DS200AAHAH2A | Second Generation ARCNET HUB LAN Driver PCB for Speedtronic Mark V LM Turbine Control System
DS200AAHAH2A is the 2nd generation AAHA ARCNET communication bare PCB board developed by GE for the legacy Speedtronic Mark V LM turbine control platform, upgraded iteration of DS200AAHAH1A series base boards. It acts as the core ARCNET bus hub inside Mark V control racks, realizing bidirectional deterministic real-time data transmission between main CPU core, local mini-operator terminal (323A2374P3), remote Genius distributed I/O stations and auxiliary drive cabinets. Compared with Gen1 DS200AAHAH1A, the 2nd generation optimizes circuit anti-interference, bus signal processing chip and power filtering circuit, supporting larger network node expansion and longer bus cable transmission distance. Each Mark V rack configures two AAHA boards for dual redundant communication to guarantee uninterrupted transmission of turbine speed, load, valve regulation and safety trip signals.
Core Technical Specifications
- Part Number: DS200AAHAH2A | Abbreviation: AAHA Gen2 | Brand: General Electric | Platform: Speedtronic Mark V LM

Main Functional Features
- Dual BNC ARCNET ports support daisy-chain network topology, expand access for more remote Genius I/O stations and local HMI mini-terminals
- Dual-board split communication architecture: one board dedicated to local operator terminal communication, one for remote distributed I/O core interconnection
- Optimized APL dedicated internal bus, higher bandwidth data exchange with all auxiliary daughterboards mounted inside the main control rack
- Upgraded multi-stage differential isolation and surge suppression circuit, stronger anti-EMI capability for high-voltage excitation and medium voltage drive cabinet environments
- Built-in full communication self-diagnosis logic, real-time alarm for bus disconnection, signal attenuation, board power loss and chip communication abnormal faults
- Supports hot-swap replacement under redundant rack configuration, no full unit shutdown required during equipment maintenance and overhaul
- Token-passing ARCNET bus cycle ensures microsecond-level real-time transmission of critical turbine control and protection interlock signals, no data collision risk
- Fully backward compatible with DS200CPU main CPU board, DS200ADPAG1 Genius adapter board and 323A2374P3 local mini operator terminal
