    GE IS220PPRAH1A Emergency Turbine Backup Protection I/O Module

    Product Description:

    The GE IS220PPRAH1A is an Emergency Turbine Backup Protection I/O Module under the Mark VIeS Series, designed for GE Distributed Turbine Control Systems. As a critical safety component, it forms an independent triple modular redundant (TMR) backup overspeed protection system—paired with the TREA terminal board and WREA option board—to safeguard turbines. It also provides a watchdog function for primary controls and isolated trip inputs, supporting IEC 61508/61511 certified safety loops. Manufactured in the U.S., it is readily available with a 3–7 day repair turnaround, suitable for both conventional and wind turbine applications.


    Key Features:
    Backup Protection & Redundancy: Operates as a TMR system (requires 3 PPRA packs on TREA/WREA) for reliable overspeed protection, preventing single/dual-pack failures. Adds 6-speed inputs for dual-speed sensors per shaft, enhancing turbine safety.


    Technical Specs: Runs on 24 V DC (≤15 W power), with 16 input channels (0–5 V) and 2 transducers. Supports 1.5 Hz pressure wave frequency, 2 Hz MPU pulse rate, and Modbus TCP/IP. Operates at -20 to +70°C, with max 15Ω lead resistance for signal integrity.


    Compatibility & Connectivity: Mounts exclusively to TREA terminal boards with WREA option board. Dual 10/100 Ethernet ports enable flexible network links—configurable for single/dual/three-controller setups.


    Reliability & Diagnostics: Equipped with a high-speed processor, hardware watchdog, internal temp sensor, and status LEDs. Soft-start power control limits inrush current; current limiting prevents fault propagation. Electronic ID checks ensure pack-terminal board compatibility.


    Industrial Design: Surface-mounted with conformal PCB coating for durability. Modular “IS220” pack-style design eases installation/maintenance, aligning with Mark VIeS’s non-legacy, versatile architecture.
