GE IS200ISBBG1AAB Insync Bus Bypass Card

د.إ8,888.00

The IS200ISBBG1AAB is a passive utility board designed to manage the system’s high-speed communication bus:

  • Bus Integrity: Its primary role is to serve as an electrical bypass for the proprietary ISBus (a high-speed synchronization bus used by GE).

  • Online Maintenance: It is used exclusively in Triple Modular Redundant (TMR) Mark VI systems (which have R, S, and T control modules). If one of the three main control modules needs to be temporarily removed for service while the turbine is running, the ISBB board is installed in its place.

  • Signal Rerouting: By occupying the vacant slot, the ISBB card passively reroutes the ISBus signals, effectively bridging the communication pathway. This ensures that the remaining two active control modules can continue to communicate and stay perfectly synchronized (InSync) without interrupting the turbine’s operation.

  • Passive Design: The board is simple, containing only passive components (conductive traces, resistors, etc.) and no active processors. This minimal design maximizes its reliability and ensures it does not introduce any lag or failure points into the critical synchronization path.

الوصف

The GE IS200ISBBG1AAB is an InSync Bus Bypass Card (ISBB) manufactured by General Electric for use in the Mark VI Speedtronic Turbine Control System.

Its function is straightforward and critical for maintaining system redundancy and allowing for online maintenance.

🔎 Revision Details

The board is a specific manufacturing version:

  • IS200: GE’s Innovation Series of control modules.

  • ISBB: InSync Bus Bypass Card.

  • G1A: Indicates the original hardware group (G1) and artwork revision (A).

  • AAB: Represents a specific assembly or manufacturing revision of the board. The core function of acting as an ISBus bypass remains the same across these minor suffixes.
