General Electric IS200TTURH1CFD(IS230TNTRH1C) Terminal Turbine Board

Configured for turbine protection, speed sensing, and breaker control in Mark VIe turbine control system platforms, the General Electric IS200TTURH1CFD(IS230TNTRH1C) (IS200TTURH1CFD(IS230TNTRH1C) Terminal Turbine Board) provides direct physical/electrical execution.

Suffix Breakdown & Model Matrix

• IS200TTURH1CFD(IS230TNTRH1C): Turbine-Specific Primary Trip Board designated as a reliable upgrade of the IS200TTURH1 supporting simplex and Triple Modular Redundant (TMR) configurations.

Hardware Specifications

Backplane Communication Velocity and Network Integration

The IS200TTURH1CFD(IS230TNTRH1C) integrates advanced interface systems and signal conditioning to preserve operational velocity and data integrity across turbine protection networks. Key design parameters include:

• Direct wiring interface to the VTUR module via JR1 and JR5 communication pathways, ensuring deterministic data exchange and minimal backplane bus communication velocity latency.
• Comprehensive I/O density scaling supporting 48 total channels via pluggable terminal blocks for TTL speed pickups, generator voltage, and shaft voltage/current signals.
• Firmware flash compatibility and hardware support for both simplex and Triple Modular Redundant (TMR) configurations.

Frequently Asked Questions

Q: Does the IS200TTURH1CFD(IS230TNTRH1C) module support live hot-swapping under power? A: No. Power must be isolated from the specific rack slot prior to module extraction or insertion to prevent backplane pin damage and transient current surges.

Q: What are the speed sensor input parameters and accuracy for this board? A: The board supports a speed sensor range from 2 Hz to 20 kHz with an accuracy of +/-0.05% and an input sensitivity of 27 mV peak for MPU inputs.

Field Installation Guidelines

• Mount the panel securely using the factory-drilled mounting holes, maintaining the specified dimensions of 305 mm x 229 mm x 76 mm.
• Terminate field instrumentation wiring onto the 2 pluggable terminal blocks, verifying correct relay configuration for K25, K25P, and K25A 125 VDC breaker systems.
• Verify that environmental conditions remain strictly within the -30 deg C to +65 deg C operating temperature window before energizing the control system.
