GE IS220PPROS1B Mark VIe Backup Turbine Protection I/O Pack (PPRO Series)

Product Description

The GE IS220PPROS1B is a critical backup turbine protection I/O pack for the Speedtronic Mark VIe control system, engineered to provide independent, redundant safety protection for gas/steam turbines in power generation and heavy industry. As a core component of turbine emergency trip systems, it operates autonomously from the primary control system, monitoring speed signals (overspeed, acceleration, deceleration) and system faults to trigger backup trip relays (TREG, TREL, TRES, TREA) within milliseconds. Featuring dual redundant Ethernet ports for high-speed communication with Mark VIe controllers, it supports simplex/dual/triple redundant architectures, ensuring operational continuity during primary control failures. Certified for hazardous areas (ATEX Zone 2, IIC Group) and compliant with IEC 61508 (SIL 3), it integrates with GE trip terminal boards, operates reliably in -20°C to 55°C environments, and offers hot-swappable functionality for minimized downtime, making it indispensable for turbine overspeed protection, emergency shutdown (ESD), and safety interlock systems.

Key Functions

The IS220PPROS1B delivers robust backup protection and safety control for Mark VIe turbine systems: Autonomous backup trip system operation, independent of primary control to ensure protection during primary system failures; Hardware-implemented overspeed, acceleration, deceleration, and basic overspeed detection for rapid fault response; Dual redundant 100MB Ethernet ports enabling high-speed data exchange with Mark VIe controllers and redundant system synchronization; Monitoring of primary control performance and primary speed verification to ensure operational integrity; Backup trip relay actuation (TREG, TREL, TRES, TREA) for emergency turbine shutdown within milliseconds; Support for simplex/dual/triple redundant system configurations to maximize availability; Hot-swappable design allowing module replacement without system shutdown, reducing maintenance downtime; Hazardous area certification (ATEX, UL) for safe operation in explosive environments; Real-time diagnostic feedback for channel health, communication links, and trip system status.

Application Scenarios

The IS220PPROS1B excels in turbine safety-critical applications: Gas/steam turbine overspeed protection systems for preventing catastrophic failures due to excessive rotational speed; Power generation plant emergency shutdown (ESD) systems for wellhead control, turbine trip, and generator protection; Oil & gas compressor safety interlocks for monitoring pressure, temperature, and anti-surge valve positions to trigger emergency shutdowns; Petrochemical refinery burner management systems (BMS) for flameout detection and fuel valve safety shutdown integration; Industrial turbine retrofits and system expansions, ensuring compatibility with existing Mark VIe controllers and trip terminal boards; Hazardous area installations requiring certified backup protection modules for safe operation in explosive atmospheres; Combined cycle power plant safety systems for integrating multiple turbine protection layers and ensuring grid stability during transient conditions.
