Description

GE IS200TPROH1C Technical Specifications:

  • Function: Safety Protection and Trip Logic.
  • System: GE Mark VI Speedtronic.
  • Redundancy: Supports TMR architecture for safety integrity.
  • Response Time: Ultra-fast trip execution (<10ms).
  • Safety Level: Designed to meet SIL (Safety Integrity Level) requirements.

Functional Features:

  • Parameter Monitoring: Continuously monitors speed, vibration, temperature, and pressure.
  • Trip Logic: Executes protective shutdowns based on predefined setpoints.
  • Voting Logic: TMR voting to prevent false trips and ensure safe operation.
  • Diagnostics: Continuous self-testing and fault reporting.

Application Scenarios:

  • Turbine overspeed protection.
  • Vibration and bearing temperature protection.
  • Lube oil pressure low protection.
  • Emergency shutdown (ESD) systems.

Performance Parameters:

  • Safety Integrity: SIL 2 or SIL 3 capable (depending on system configuration).
  • Reliability: Extremely high MTBF for safety-critical functions.
  • Response: Deterministic and guaranteed trip times.

Material Composition & Structural Characteristics:

  • PCB: High-reliability board with safety-critical component selection.
  • Components: Redundant processors and voting logic circuits.
  • Connectors: Secure backplane and field connections.
  • Enclosure: Ruggedized protection board housing.

Working Principle: The board receives critical safety signals from redundant sensors. The TMR voting logic compares the signals and determines if a trip condition exists. If a valid trip is detected, the board immediately energizes the trip solenoids to shut down the turbine. Continuous self-diagnostics ensure the board is always ready to protect the machine.

Installation Requirements:

  • Safety Procedures: Follow strict safety protocols for safety-critical equipment.
  • Wiring: Use redundant wiring for safety sensors.
  • Testing: Perform comprehensive safety system testing before commissioning.
  • Documentation: Maintain detailed safety system documentation.

Usage Precautions:

  • Safety Critical: Never bypass or defeat safety functions without proper authorization.
  • Testing: Regularly test the protection system to verify functionality.
  • Replacement: Use only factory-calibrated safety boards.
  • Training: Ensure personnel are trained in safety system operation and maintenance.
