Product Overview
The GE IS200TRPAH1A is a high-reliability primary trip terminal board engineered for aeroderivative gas and steam turbine control systems, serving as a core component of GE’s Mark VIe platform. Designed to execute critical turbine protection logic, this board integrates with PTUR/YTUR I/O packs and TTUR terminal boards to monitor turbine health parameters and trigger emergency shutdowns (ESD) when 异常 conditions are detected. Its dual operational modes—direct I/O pack integration or TTUR-based TMR configurations—provide flexibility for both simplex and redundant system designs, ensuring fail-safe actuation in power generation, oil & gas, and industrial process applications.

Dual-Mode Trip Logic: The GE IS200TRPAH1A supports two configurations:
- TTUR-TMR Mode: Connected via TTUR terminal boards, it provides three independent relay banks (R/S/T) that vote on trip signals, ensuring redundancy for critical ESD systems.
- Direct I/O Mode: Directly interfacing with PTUR/YTUR packs, it offers simplex actuation for non-safety-critical applications, reducing hardware complexity.
- Four voltage detection circuits continuously monitor trip strings for anomalies like undervoltage or open circuits, with thresholds configurable via GE’s Proficy software.
- Six passive pulse rate inputs analyze turbine speed using toothed wheel sensors, supporting overspeed protection up to 115% of rated speed.
The GE IS200TRPAH1A excels in high-risk turbine applications requiring rapid, reliable trip logic:
- Power Generation: Monitors gas turbine fuel systems, triggering shutdowns during flameout or compressor surge events. Its voltage detection capability ensures compliance with API 670 vibration monitoring standards.
- Oil & Gas: Integrates with BOP (blowout preventer) systems on offshore rigs, providing redundant actuation for hydraulic control valves. The board’s wide input voltage range supports legacy 125 V DC control systems.
- Industrial Process: Manages steam turbine-driven pumps in chemical plants, using pulse rate inputs to detect shaft displacement and prevent catastrophic seal failures.

Pre-Installation Preparation:
- Verify power supply compatibility and ground connections using GE’s Mark VIe wiring diagram (GEH-6721).
- Configure jumpers JP1/JP2 to fan out pulse rate signals to PTUR/YTUR packs in TMR mode.
- Perform quarterly voltage detection circuit calibration using GE’s Proficy software.
- Replace relays every 5 years or after 500,000 operations to maintain contact integrity.
- Inspect terminal block torque annually to prevent loose connections in high-vibration environments.
GE guarantees the IS200TRPAH1A with a 2-year warranty for new/repaired units and a 3-year warranty for remanufactured units, covering material defects and workmanship. The board undergoes rigorous testing to meet UL 508 and IEC 61131-2 standards, ensuring compliance with global safety protocols. GE’s 24/7 technical support network provides rapid troubleshooting and replacement services, minimizing downtime in critical applications.
