GE IS200VTURH2BAB – Turbine Protection Circuit Board

Overview

The GE IS200VTURH2BAB is a turbine protection circuit board used in the Mark VI Turbine Control System, part of GE’s Speedtronic series. It plays a key role in turbine safety and synchronization functions, offering precise control of overspeed protection, automatic synchronizing, and multiple application-specific inputs and outputs.

Key Features

• Designed for gas, steam, and wind turbines
• Controls 3 primary overspeed trip solenoids
• Supports automatic synchronizing
• Accepts pulse rate speed inputs from 4 magnetic speed sensors
• Supports shaft voltage, current monitoring, and trip breaker interfaces
• Capable of interfacing with up to 8 flame detectors
• Compatible with Honeywell flame scanners (uses 335 VDC power supply)
• Built for VME rack mounting in Mark VI systems
• Equipped with metal faceplate and 3 diagnostic LEDs:
  • RUN
  • FAIL
  • STAT

Functional Applications

• Overspeed Protection: Monitors turbine speed and triggers solenoid shutdown
• Flame Detection Monitoring: Detects low light levels and carbon contamination
• Breaker Interface & Synchronization: Interfaces with PTs and synchronizes with grid
• Solenoid Driver I/O: Controls critical turbine safety shutdown paths

Compatible Barrier Boards

• TRPG
• TRPS
• TRPL
• TTUR
  These boards connect the VTUR I/O to the Control Module for reliable operation.

Hardware & Design

• Mounts into standard Mark VI VME Rack
• Supports barrier-type I/O terminations
• Revised from original VTUR board, with H2 hardware revision and BAB revision level
• Durable construction with enhanced diagnostics via onboard LEDs
