DS200SLCCG3AGH GE Mark V LAN Communication Card

Product Overview

The GE DS200SLCCG3AGH functions as the primary LAN Communication Card (SLCC) for the GE Speedtronic Mark V turbine control system and compatible AC/DC high-power drives. This board manages the high-speed data traffic between the drive control board and the external Local Area Network (LAN). By acting as the intelligent interface for the ARCNET protocol, the DS200SLCCG3AGH ensures deterministic communication and real-time synchronization across multiple control nodes. We supply this module as 100% Brand New, ensuring factory-calibrated performance for critical infrastructure where system uptime is non-negotiable.

Technical Specifications

The DS200SLCCG3AGH features a dedicated microprocessor architecture and socketed EPROM chips for flexible firmware management.

Engineering Advantages

• High-Speed Deterministic Control: The SLCC board utilizes the ARCNET protocol to provide collision-free data transmission. This ensures that critical turbine parameters and drive commands reach their destination with sub-millisecond consistency, preventing jitter in high-performance control loops.

• Local Diagnostic Visualization: The onboard 4-digit LED display provides immediate feedback on communication status and internal faults. This allows technicians to troubleshoot network errors directly at the cabinet door without connecting external diagnostic software.

• Plug-and-Play Maintenance: The board mounts directly onto the drive control board via several multi-pin headers. This vertical stacking design eliminates complex internal wiring and allows for rapid "hot-swap" preparation (when the system is de-energized), significantly lowering the Mean Time To Repair (MTTR).

• Advanced Noise Mitigation: The "AGH" revision indicates specialized hardware hardening against electromagnetic interference (EMI). This is crucial in environments with high-power SCR switching where electrical noise often compromises standard communication signals.

FAQs

• Can I swap the EPROM chips from my old SLCC board to this new one?

  Yes. The DS200SLCCG3AGH features socketed PROMs. To maintain your specific site configuration and ARCNET node address, you should carefully migrate the EPROM chips from the original board to the new assembly using an anti-static extractor tool.

• What is the purpose of the Berg jumpers on this board?

  Jumpers like JP1 and JP2 define the hardware configuration, such as enabling the serial port or setting the oscillator frequency. Always match the jumper positions of the new board exactly to those of the board you are replacing.

• Does this board support the Mark V  or  interface?

  The SLCC provides the underlying LAN physical layer. While it does not "run" the HMI, it is the essential gateway that allows the HMI to pull data from the turbine control cores (, , ).

• How do I verify the LAN node address?

  The node address is typically stored in the EPROM or set via software parameters during commissioning. Upon power-up, the 4-digit LED display will often scroll through initial self-test codes and the detected node identity.
