IS200TREAH2AED GE Mark VIe Turbine Emergency Trip Board

GE IS200TREAH2AED – Mark VIe Turbine Emergency Trip Terminal Board

Key Technical Specifications

• Product Type: Turbine Emergency Trip Terminal Board for GE Mark VIe systems.
• Speed Sensing: Nine passive pulse rate devices (3 per X/Y/Z section) measure turbine speed via toothed wheel.
• Voting Output Contacts: TMR voted contacts at 24 V dc and 125 V dc for emergency trip execution.
• Voltage Monitors: Four 24–125 V dc detection circuits plus three general-purpose isolated sensor inputs.
• Terminal Type: Plug-in barrier blocks (24-point) or Euro-style box terminals (48-point) for flexible wiring.
• Temperature Range: -30 to 65 °C with high resistance to industrial electrical noise.
• Physical Size: 33.0 cm high x 17.8 cm wide, manufactured in the USA.
• Technology: Surface mount design for enhanced durability and compactness.

Functional Features for Turbine Control

• Redundant Trip Relays: Each set uses six form devices in a 2-out-of-3 voting pattern to ensure reliable tripping.
• Short-Circuit Detection: Sensing circuits detect relay shorting and trigger alarms via the PPRO I/O pack.
• Jumper Blocks: Fan one set of speed inputs to all three PPRO packs for synchronization and redundancy.
• Daughterboard Connectors: Enable optional expansion for future feature upgrades.
• Voltage Monitoring Applications: Monitor power supply (PWR) and solenoid voltage (SOL1, SOL2) to verify system integrity.
• Customer Input Terminals: Accessible through two 24-point pluggable barrier terminal blocks (H1A, H2A) or 48 pluggable Euro-style box terminals (H3A, H4A).

Frequently Asked Questions

• Q: Are these boards new or refurbished?
  A: We supply only new original GE boards, directly from factory stock.
• Q: What is the typical lead time for delivery?
  A: We ship within 5 days after order placement, with express courier options available.
• Q: Can I use this board with a different control system?
  A: The IS200TREAH2AED is specifically designed for GE Mark VIe systems; compatibility with other platforms is not supported.
• Q: How do I wire the voltage detection circuits?
  A: Connect the 24–125 V dc signals to the designated terminals; the board provides isolated inputs for monitoring.
• Q: What happens if a relay shorts?
  A: The built-in sensing circuit detects the fault and sends an alarm to the PPRO I/O pack for operator notification.
• Q: Do you offer technical support for installation?
  A: Yes, our team provides application notes and wiring diagrams; contact us for detailed assistance.
• Q: What is the temperature range for operation?
  A: The IS200TREAH2AED operates reliably from -30 to 65 °C in industrial environments.
