Product Overview
The GE IS200TRLYH2F is a high-reliability relay output terminal board engineered for mission-critical turbine control systems, part of GE’s advanced Mark VI platform. Designed with triple modular redundancy (TMR) contact voting functionality, this module ensures fail-safe operation in applications where equipment integrity and process continuity are paramount. Unlike its Form A (NO) counterpart, the GE IS200TRLYH2F features 12 contact-voted relay outputs configured as Form B (Normally Closed), making it ideal for safety-critical systems where de-energization triggers protective actions.

Integrated into the Mark VI architecture, the GE IS200TRLYH2F supports both simplex and TMR configurations, allowing users to tailor system resilience based on risk tolerance. Each TMR segment houses 12 sealed relays (36 total), which combine to form a voted Form B output that minimizes single-point failures. The board’s dual voltage compatibility (120 V AC or 28/125 V DC inputs) ensures adaptability across global industrial environments, from power generation to oil & gas processing. Its design prioritizes diagnostic transparency, with real-time monitoring of relay coil currents to detect anomalies proactively.

Key Features and Advantages
TMR Contact Voting with Form B Output: The GE IS200TRLYH2F employs three independent relay banks (R, S, T) that vote on control signals, ensuring reliable actuation even if one segment fails. Its Form B configuration inherently supports fail-safe logic, where loss of power triggers protective actions, critical for emergency shutdown systems in hazardous industries.

Dual Voltage Compatibility: With support for both AC and DC inputs, the board eliminates the need for additional voltage converters, streamlining integration into diverse industrial environments.

Real-Time Diagnostics: Built-in coil current monitoring detects discrepancies between commanded and actual relay states, enabling predictive maintenance and reducing unplanned downtime. This feature aligns with GE’s proactive approach to system health management.

Modular Design: The DIN rail-mountable form factor allows easy integration into existing control cabinets, while field-replaceable relays simplify repairs without system shutdowns. The rugged, corrosion-resistant enclosure ensures longevity in extreme temperatures and high-vibration settings.

Application Areas
The GE IS200TRLYH2F excels in safety-critical scenarios requiring fail-safe control:

Installation and Maintenance
Pre-Installation Preparation: Verify power supply compatibility and ensure proper grounding. Align the GE IS200TRLYH2F with the Mark VI I/O rack using DIN rail brackets, securing all connectors (JR1, JS1, JT1) for TMR configurations.

Maintenance Recommendations: Conduct quarterly inspections to check relay contact resistance and verify TMR voting logic. Replace relays every 5 years or after 100,000 operations to maintain optimal performance. Update firmware biannually to leverage GE’s latest diagnostic algorithms.

Product Assurance
GE guarantees the IS200TRLYH2F with a 1-year warranty 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.
