GE DS200SLCCG4A
Product Name: GE DS200SLCCG4A Mark V LAN Communication Card (SLCC)
Product Overview: The DS200SLCCG4A is a LAN Communication Card (SLCC) for GE’s Speedtronic Mark V turbine control system. It provides complete ARCNET and DLAN network connectivity for GE drive systems and exciters in turbine control cabinets, enabling communication between Mark V control boards and the broader plant network or local HMI.

NOTE: Some secondary-market sources describe the DS200SLCCG4ACC variant as a multi-input PC control board with dual Ethernet ports, four serial channels (RS-232/485), 32-bit ARM 200 MHz processor, 16 MB SDRAM / 8 MB Flash, and support for Modbus TCP/RTU, Profibus, GE SRTP, and DNP3 protocols, with dimensions of 210 × 150 × 30 mm, operating temperature 0°C to +50°C. This multi-port configuration information may apply to the DS200SLCCG4ACC variant.
Functional Features:
- Provides complete LAN communication interface for Mark V drive/exciter systems
- Supports ARCNET and DLAN network protocols
- Critical for networked turbine control operations
- Allows replacement of failing LAN communication interfaces
Performance Parameters:
- Operating temperature: 0°C to +50°C (typical Mark V cabinet environment)
- Stable operation under minor power fluctuations
Material & Structural Characteristics:
- PCB-based communication card designed for Mark V card-file mounting
- Integrated ARCNET and DLAN interface circuitry
Working Principle: The card interfaces the Mark V control system to the plant ARCNET or DLAN network, handling communication between the turbine controller, exciters, drives, and higher-level HMI or plant control systems. It translates and routes network messages to maintain synchronized operation across the Mark V architecture.
Installation Requirements:
- Install in designated Mark V card-file slot
- Photograph old card’s connector position and jumper settings before replacement
- Note the rack slot location and verify power is off before installation
- Check the ARCNET hub/switch status
Usage Notes:
- Verify exact model and revision before installation to ensure compatibility
- LAN cards are sensitive to address and termination mismatches—verify network address jumpers, cable connector type, and backplane slot
- Only install as direct replacement if the existing system uses DS200SLCCG4A in the same Mark V configuration
- Bad swaps often result from assuming network address compatibility; always verify before installation
