The GE DS215SLCCG2AZZ01B LAN Communications Card is a critical, highly-integrated printed circuit board (PCB) assembly used in General Electric’s industrial control and drive systems.
It is the Standard LAN Communication Card (SLCC) within the GE Speedtronic Mark V Turbine Control System and associated drive/exciter platforms (AC2000, DC2000, and EX2000).
⚙️ Core Functions and Features
| Feature | Specification/Description |
| Product Type | LAN Communications Card / Network Interface Card (NIC) |
| Series/Family | GE Speedtronic Mark V Turbine Controls and Industrial Drives |
| Core Function | Real-time Network Connectivity. Manages the flow of control, monitoring, and diagnostic data over the system’s local network, ensuring reliable, high-speed communication between processors and I/O. |
| Microprocessor | Features a dedicated LAN Control Processor (LCP), which uses software stored on EPROM chips to handle network traffic and offload communication duties from the main control processors. |
| Operator Interface | Includes a dedicated connector (KPPL) to interface with a programmer module keypad and an on-board 16-position alphanumeric display for local, on-site diagnostics and configuration. |
| Network Support | Primarily used to support the industrial network protocols essential for the drive/turbine control, such as DLAN (Drive Local Area Network). |
| Revision Details | The G2 specifies the Group 2 hardware revision, and the AZZ01B suffix confirms the specific GE firmware package loaded onto the board. The ‘B’ revision denotes a functional or software update from the ‘A’ version. |
| Circuits | Contains both isolated and non-isolated circuits for communication, which helps enhance noise immunity and reliability in harsh industrial settings. |
This board is fundamental to the fault-tolerant and distributed control architecture of the Mark V system, providing both high-speed communication and a direct local interface for technicians.
