Product Description
Product: DS200AAHAH1A – GE Mark V AAHA ARCNET Hub Communication Board
GE DS200AAHAH1A | ARCNET LAN Driver Interface Card for Speedtronic Mark V Turbine Control System
DS200AAHAH1A (AAHA Board) is a dedicated ARCNET communication hub circuit board developed by GE for the classic Speedtronic Mark V LM turbine control platform. It acts as the core protocol conversion bridge between the rackmain control engine, internal I/O cores, local mini-terminal HMI and remote distributed ARCNET field devices. Each Mark V control rack is equipped with two AAHA boards for dual redundant communication: one connects the main CPU core to local operator panels, the other links the main engine to remote Genius I/O stations and auxiliary drive cabinets, realizing stable bidirectional real-time data transmission based on industrial ARCNET bus protocol.
Core Technical Specifications
