The General Electric IS220PPROS1B is an Emergency Turbine Protection I/O Pack designed for the Mark VIe control system. This module serves as an independent, high-reliability watchdog, providing backup overspeed protection for both gas and steam turbines. It continuously monitors the primary control system's performance and provides a secondary check for generator synchronization to the utility bus.

Features

  • Emergency turbine protection with integrated backup overspeed monitoring.
  • Triple Modular Redundant (TMR) architecture support for high-availability applications.
  • Hardware-implemented protection for acceleration, deceleration, and overspeed conditions.
  • Dual independent 10/100 Ethernet ports for IONet communication.
  • Soft-start input power circuitry with integrated current limiting.
  • Independent monitoring of trip board status via comprehensive feedback signals.

Applications

  • Gas and steam power generation plants for turbine failure prevention.
  • Hydroelectric power generation for turbine speed and grid synchronization.
  • Industrial cogeneration facilities requiring high-availability backup systems.
  • Hazardous environments requiring robust temperature tolerance and electrical isolation.

Installation Guidelines

  • Ensure the system is powered down before inserting or removing the I/O pack from the terminal board.
  • In TMR configurations, ensure all three I/O packs are correctly seated on their respective SPRO terminal boards.
  • Connect Ethernet cables to the designated IONet ports; the module automatically manages network redundancy.
  • Use DC-37 pin cables for connections between the SPRO terminal board and the emergency trip board.
  • Maintain proper ventilation to ensure the module operates within its specified temperature range.
  • Configure the module parameters using the GE ToolboxST software suite.

FAQ

What is the primary purpose of the IS220PPROS1B?

It acts as an independent backup protection system that monitors primary turbine speed and the status of trip terminal boards, initiating a trip on the primary control if a fault is detected.

Can this module be used in TMR systems?

Yes, it is fully compatible with both Simplex and Triple Modular Redundant (TMR) systems. In TMR setups, three PPRO packs are typically mounted to separate SPRO terminal boards.

What communication interfaces are included?

The module features two independent 10/100 Ethernet ports used to link directly into the control module's internal IONet network.
