The GE DS215SLCCG1AZZ01A LAN Communications Card is a vital, highly specialized circuit board used in General Electric’s legacy industrial control platforms, most notably the Speedtronic Mark V Turbine Control System and associated drive/exciter systems (like the AC2000, DC2000, and EX2000).
The functional acronym for this card is SLCC (Standard LAN Communication Card).
⚙️ Key Functions and Specifications
| Feature | Specification/Description |
| Product Type | LAN Communications Card / Network Interface Card (NIC) |
| Series/Family | GE Speedtronic Mark V Turbine Controls and Drives |
| Core Function | Network Connectivity and Data Exchange. It manages the flow of real-time control, monitoring, and diagnostic data between the main control processors and the rest of the system. |
| Supported Networks | Includes circuitry to connect the drive/exciter to industrial networks like DLAN (Drive Local Area Network) and ARCNET. |
| Microprocessor | Features a dedicated LAN Control Processor (LCP), whose software is stored in two replaceable EPROM slots. This processor handles network traffic, relieving the main control processors. |
| Operator Interface | This card is critical for local access. It has a dedicated connector (KPPL) to interface with a programmer module keypad and an on-board 16-position alphanumeric display for diagnostics and parameter access. |
| Circuits | Contains both isolated and non-isolated circuits for communications to the drive or exciter, ensuring noise immunity in industrial settings. |
| Firmware | The suffix AZZ01A confirms it is pre-loaded with the specific GE firmware package required to define its operational and network logic. |
| Instruction Manual | The relevant manual for this card is GEI-100162 (often seen as GEI-100162B). |
The DS215SLCCG1AZZ01A is essential for maintaining seamless, reliable communication and providing the ability to perform on-site diagnostics and configuration of the turbine or drive control system.
Since this component is discontinued by GE, but vital for existing industrial installations, support is focused on the specialized repair and surplus market.
