Product Description
Product: DS200AAHAH1AED – GE Mark V AAHA ARCNET Hub Communication Assembly Board
GE DS200AAHAH1AED | Full Assembled ARCNET Communication Card for Speedtronic Mark V Turbine Control System
DS200AAHAH1AED is the complete assembled revision of the GE AAHA ARCNET communication board under the Speedtronic Mark V platform. The base bare PCB model is DS200AAHAH1A, while suffix ED represents full assembled hardware revision E and drawing revision D, fully fitted with all original components, connectors, isolation circuits and conformal coating. It serves as the redundant ARCNET bus hub inside Mark V control racks, realizing bidirectional real-time communication between main CPU, local mini-operator terminals (323A2374P3), Genius remote I/O stations and auxiliary drive cabinets. Two AAHA boards are deployed in one rack for dual communication redundancy to guarantee uninterrupted data transmission of turbine speed, load, valve regulation and protection interlock signals.
Core Technical Specifications
- Full Part Number: DS200AAHAH1AED | Base PCB: DS200AAHAH1A | Abbreviation: AAHA | Brand: General Electric | Platform: Speedtronic Mark V LM

Main Functional Features
- Dual BNC ARCNET ports support daisy-chain topology, expand access for multiple remote Genius I/O stations and local HMI terminals
- Dual-board split communication architecture: one board for local mini-terminal operation communication, one for remote distributed I/O interconnection
- APL dedicated internal bus realizes high-speed data exchange with all auxiliary daughterboards mounted inside the main control rack
- Integrated signal isolation and surge suppression circuits, suppress high-frequency EMI interference from high-voltage excitation and medium voltage drive cabinets
- Built-in communication self-diagnosis logic, real-time alarm for bus disconnection, signal attenuation and board power loss faults
- Supports hot-swap replacement under redundant rack configuration, no full unit shutdown required during equipment maintenance and overhaul
- Deterministic ARCNET bus cycle ensures microsecond-level real-time transmission of critical turbine control and protection signals
- Full compatibility with DS200CPU main CPU board, DS200ADPAG1 Genius adapter board and 323A2374P3 local mini operator terminal
