General Electric IS200TTURH1C Terminal Turbine Board

Product Overview

The GE IS200TTURH1C is a Turbine Control Terminal Board for the Mark VI and Mark VIe Speedtronic systems. It provides generator synchronization and trip logic interfacing through hardware mechanisms and interconnections, featuring three onboard relays, six 37-pin interfaces, and two centrally positioned transformers. The board supports configurable simplex or TMR voting via jumper switches, making it adaptable to both standard and redundant turbine control architectures. Note: This is a synchronization/trip terminal board, not a primary speed control module.

Installation Guide

1. Mount the IS200TTURH1C in a standard Mark VI/VIe rack.
2. Set jumper switches for simplex or TMR voting according to system architecture.
3. Connect 37-pin cables to PTUR and VTUR boards for turbine control interconnection.
4. Verify relay operation and transformer continuity using diagnostic tools.
5. Perform synchronization tests to confirm proper generator paralleling functionality.

FAQ

• Q: What does TTUR stand for?
  A: TTUR is the functional acronym for Turbine Trip/Control Terminal Board, handling synchronization and trip logic interfacing.
• Q: Is TTUR a speed control board?
  A: No. TTUR is a terminal board for synchronization and trip circuits. Primary turbine speed control is handled by dedicated processor boards such as the TMR controller.
• Q: How is TMR voting configured?
  A: TMR voting is enabled via onboard jumper switches; consult the Mark VI installation manual for specific jumper positions.
• Q: What boards does TTUR interface with?
  A: It communicates with PTUR (Primary Turbine) and VTUR (Vibration/Turbine) boards via D-shell connectors and terminal blocks.

Selection Tips

• Use IS200TTURH1C for generator synchronization and turbine trip interfacing in Mark VI/VIe systems.
• Ensure jumper settings match the redundancy architecture (simplex vs. TMR) before installation.
• Pair with compatible PTUR/VTUR boards for complete turbine control functionality.
