This critical hardware safety asset connects the central control processors directly to the main hydraulic trip solenoids of the turbine assembly. It accepts diagnostic trip commands from the primary control core, executing emergency shutdown routines by instantly cutting power to the fuel and steam valves when safety thresholds crack. The board incorporates triple redundant voting mechanics at the relay level to guarantee execution, ensuring that failing individual relays cannot prevent a valid trip or cause an accidental, expensive false shutdown. Heavy utility operators, combined-cycle power generating facilities, and industrial pipeline compression stations deploy this component to safeguard multi-million dollar rotating machinery from catastrophic overspeed, loss of lubrication, or thermal runaway events.\u003c\/p\u003e\n\u003ch3\u003ePart Number Breakdown\u003c\/h3\u003e\n\u003cp\u003eThe alpha-numeric identification code details the specific engineering revision, physical hardware configuration, and exact control block placement within the Mark VI panel layout:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIS200:\u003c\/strong\u003e Identifies the standard manufacturing architecture and baseline component catalog grouping within GE Industrial Systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTRPG:\u003c\/strong\u003e Designates the specific functional board application as a Turbine Primary Trip Relay Termination board assembly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eH1:\u003c\/strong\u003e References the base electrical circuit design, terminal block layout arrangement, and system compatibility profile.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eB:\u003c\/strong\u003e Marks the exact hardware revision tier, reflecting factory component selection updates and optimized tracking path layouts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDE:\u003c\/strong\u003e (When appended as IS200TRPGH1BDE) Specifies the exact firmware alignment, conformal environmental coating level, and regional factory inspection certifications.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e IS200TRPGH1B (Directly matches functional configurations like IS200TRPGH1BDE)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e General Electric (GE)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e Mark VI Speedtronic Control System\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Condition:\u003c\/strong\u003e 100% Brand New Original\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Primary Trip Relay Termination Board\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e United States\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 330 mm H x 178 mm W x 76 mm D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNet Weight:\u003c\/strong\u003e 1.45 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Output Configuration:\u003c\/strong\u003e Drives up to three independent hydraulic trip solenoid valves (ETVs)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelay Interlocking Voting Array:\u003c\/strong\u003e Implements full hardware-based 2-out-of-3 (2oo3) relay voting matrix\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Control Signals:\u003c\/strong\u003e Connects via specialized ribbon cables to the primary R, S, and T control processors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiagnostic Telemetry Monitoring:\u003c\/strong\u003e Tracks trip circuit continuity, relay coil current status, and contact positioning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Interface Blocks:\u003c\/strong\u003e Two heavy-duty barrier-style terminal strip rails accepting 12 AWG field wiring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Ambient Temperature:\u003c\/strong\u003e 0 to 60 deg C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStorage Ambient Temperature:\u003c\/strong\u003e -40 to 70 deg C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelative Humidity Threshold:\u003c\/strong\u003e 5 % to 95 % maximum limit, non-condensing atmosphere\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eEngineering Advantages\u003c\/h3\u003e\n\u003cp\u003eThe IS200TRPGH1B board introduces definitive hardware structures to resolve demanding safety-critical turbine isolation issues:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardware-Based 2oo3 Voting Circuit:\u003c\/strong\u003e The board routes control lines through a cross-strapped matrix of nine independent, sealed safety relays. This hardware-level layout executes a full 2-out-of-3 voting architecture. If one processing core generates a rogue trip command or an individual relay contact welds shut, the board suppresses the false action while maintaining the capacity to shut down the turbine immediately if a true emergency occurs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComprehensive Trip Circuit Diagnostics:\u003c\/strong\u003e The system continuously injects low-current, non-disruptive monitoring pulses through the external trip solenoid coils. This active tracking senses broken field wires, high-resistance connections, or shorted coils while the turbine runs, warning operators of an installation fault before they ever require an emergency trip execution.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Barrier-Style Wire Termination:\u003c\/strong\u003e High-density, rugged barrier terminal strips line the edge of the card, accepting direct ring-lug connections up to 12 AWG. This mechanical design eliminates common loose-wire failures under severe, high-frequency structural vibration and provides a testable interface point for field maintenance teams.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated Spark and Surge Suppression:\u003c\/strong\u003e Parallel metal-oxide varistors (MOVs) and free-wheeling diode networks cross every inductive relay contact path. This architecture clamps massive back-EMF voltage spikes generated when heavy inductive solenoid coils de-energize, protecting nearby analog signal runs from high-frequency electromagnetic cross-talk.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFAQs\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCan this IS200TRPGH1B board replace older versions like the H1A without software modification?\u003c\/strong\u003e Yes. The IS200TRPGH1B offers complete backward functional compatibility with the initial H1A release. It retains the identical physical footprint, ribbon connection pinouts, and field wiring terminal assignments, allowing maintenance technicians to slide it directly into existing Mark VI termination racks without altering the system configuration files.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat specific precautions should an engineer follow when connecting field cables to this board?\u003c\/strong\u003e Always isolate the external 125 VDC or 24 VDC solenoid power supplies before attaching field wires to the barrier terminal strips. Technicians must route the primary processor ribbon cables from the R, S, and T racks into their exact matching connectors on the card to maintain correct phase assignment for the internal 2-out-of-3 hardware voting logic.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHow does this card communicate its diagnostic data back to the operator interface (HMI)?\u003c\/strong\u003e The board monitors its own internal relay contact states and voltage levels constantly. It streams these status registers back through the control ribbon cables directly to the main I\/O board. The processor analyzes these inputs and immediately generates alarm logs on the operator station if any single relay contact fails to match its commanding processing core.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GE Fanuc","offers":[{"title":"Default Title","offer_id":53495303766200,"sku":"IS200TRPGH1B","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0935\/6132\/3704\/files\/IS200TRPGH1B_2_1.jpg?v=1779443437","url":"https:\/\/www.globalpetroparts.com\/products\/is200trpgh1b-ge-mark-vi-primary-trip-termination-board","provider":"Global Petro Parts Automation","version":"1.0","type":"link"}
