The GE DS215SLCCG4AZZ01A LAN Communications Card is a vital, highly specialized circuit board used in General Electric’s legacy industrial control platforms. It is the Standard LAN Communication Card (SLCC) within the GE Speedtronic Mark V Turbine Control System and associated drive/exciter systems.
The G4 in the part number indicates a Group 4 hardware revision, representing an evolution from earlier G1 and G2 versions of the board.
⚙️ Key Functions and Specifications
| Feature | Specification/Description |
| Product Type | Standard LAN Communication Card (SLCC) / Network Interface Card (NIC) |
| Series/Family | GE Speedtronic Mark V Turbine Controls and Industrial Drives (AC2000, DC2000, EX2000) |
| Core Function | Real-time Network Connectivity. Manages the flow of control, monitoring, and diagnostic data over the system’s local network (DLAN), ensuring high-speed communication between processors, I/O, and the Human-Machine Interface (HMI). |
| Microprocessor | Features a dedicated LAN Control Processor (LCP), whose primary job is to handle network traffic and offload communication duties from the main control processors. |
| Operator Interface | This card is critical for local access. It includes a dedicated connector (KPPL) to interface with a programmer module keypad and an on-board 16-position alphanumeric display for diagnostics, parameter access, and on-site configuration. |
| Revision Details | The G4 specifies the Group 4 hardware revision. The AZZ01A suffix confirms the specific GE firmware package loaded onto the board, defining its operational and network logic. |
| Architecture | It is designed to plug into the modular architecture of the Mark V’s VME rack or to mount onto a main control card (like the SDCC). |
| Discontinued Status | Like all DS215 boards, it is a legacy component that is discontinued by the original manufacturer, requiring support from the specialized industrial repair and surplus market. |
In summary, the DS215SLCCG4AZZ01A is indispensable for reliable network communication and crucial for local troubleshooting of the Mark V turbine or drive control system.
