د.إ8,888.00

The IS200ISBBG1AAA is a passive utility board used to maintain system redundancy and integrity.

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

  • Online Maintenance: It is installed when one of the main control modules (typically the R, S, or T modules in a Triple Modular Redundant, or TMR, Mark VI system) is temporarily removed for repair, replacement, or maintenance while the turbine is running.

  • Signal Rerouting: By plugging into the empty slot, the ISBB card passively reroutes the ISBus signals, effectively bridging the communication path. This ensures that the remaining two control modules can continue to communicate and stay perfectly synchronized (InSync) without interruption, maintaining the system’s high reliability.

  • Passive Design: The board is intentionally simple, containing mostly passive electrical components (like resistors and conductive traces) and no active processors or complex circuitry. This minimal design maximizes its reliability and ensures it does not introduce any processing lag or potential failure points into the critical communication path.

الوصف

The GE IS200ISBBG1AAA is an InSync Bus Bypass Card (ISBB) manufactured by General Electric, designed specifically for use in the Mark VI Speedtronic Turbine Control System.

Its function is straightforward but critical: it ensures the high-speed communication bus remains operational when a key component is removed for maintenance.

🔎 Revision Details

The board is an evolution of the base design:

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

  • ISBB: InSync Bus Bypass Card.

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

  • AAA: Represents a specific manufacturing assembly or minor production revision of the board. The core function of acting as a bus bypass remains unchanged across these minor suffixes.
