1. Product Overview
DS200SLCCG1AFG (SLCC = System LAN Communication Card) is a dedicated dual-network communication core board for GE Speedtronic Mark V turbine drive and excitation control cabinets, acting as the dedicated network gateway between the main DMC redundant processor and all drive, exciter and auxiliary I/O sub-modules in the rack.
This G1-generation hardware variant integrates complete DLAN and ARCNET dual protocol circuits, equipped with independent LCP (LAN Control Processor) to undertake all network data computing tasks, reducing the operation load of the main DMC CPU. Onboard dual-port RAM serves as high-speed data cache for bidirectional real-time transmission of turbine speed control commands, excitation current regulation parameters, analog sampling values and equipment fault alarm signals.
Two replaceable EPROM chips solidify dedicated communication firmware matching the unit’s turbine configuration; isolated and non-isolated signal isolation circuits are built in to adapt to mixed industrial network wiring environments. Multi-group LED status indicators display DLAN/ARCNET link running status, communication packet loss and hardware failure alarms for on-site maintenance troubleshooting.
Full IPC-CC-830 conformal coated PCB, gold-plated rack edge connectors, anti-corrosion and moisture-proof industrial design, suitable for long-term stable operation in high-EMI power plant cabinet environments. It cannot operate independently and must be matched with Mark V DMC main CPU board, rack backplane, power supply module, drive control boards and exciter cards to form a complete turbine drive control system.
This model belongs to discontinued legacy spare parts for old Mark V turbine units, mainly supplied as refurbished, surplus and remanufactured circuit boards for power plant overhaul and routine maintenance replacement.
