Description
GE IS200TRLYH1B Relay Output Terminal Board
The IS200TRLYH1B is a high-performance relay output terminal board designed by General Electric (GE) for its Mark VI turbine control system. This module serves as a critical component in industrial automation, enabling reliable control of high-power devices such as solenoids, valves, and motors in demanding environments. With its advanced relay configuration and robust design, the IS200TRLYH1B ensures seamless integration and efficient operation in industries like power generation, oil & gas, and manufacturing.
1. Product Description
The IS200TRLYH1B is a compact, DIN-rail mountable module featuring 12 plug-in magnetic relays for precise control of external devices. It supports 125V DC, 115/230V AC, and 24V DC power inputs, making it versatile for diverse applications 59. The module includes surge protection via Metal Oxide Varistors (MOVs) to guard against voltage spikes, optical isolation to prevent ground loops, and status LEDs for real-time diagnostics. By integrating with GE’s Mark VI control platform, the IS200TRLYH1B streamlines system configuration and reduces commissioning time.

3. Advantages and Features
- High Reliability: The IS200TRLYH1B incorporates military-grade components and undergoes rigorous testing, achieving a Mean Time Between Failures (MTBF) of 150,000 hours 5. Its dual-channel redundancy design ensures continuous operation even if one channel fails.
- Flexible Configuration: Users can toggle between solenoid driving and dry contact modes for the first six relays, adapting to various actuator requirements without hardware changes 9. The module also supports both simplex and Triple Modular Redundant (TMR) systems, enhancing fault tolerance in critical applications.
- Safety Features: Onboard suppression and individual jumper-selectable fuses protect against overcurrent and voltage surges, meeting Class I, Division 2 hazardous location standards 7.
4. Application Areas and Application Cases
- Power Generation: Controls turbine auxiliary systems (e.g., lubrication pumps, cooling fans) and emergency shutdown valves in gas/steam turbines.
- Oil & Gas: Manages high-pressure solenoid valves in offshore platforms and refineries.
- Manufacturing: Operates robotic arms and conveyor systems in automotive plants.
Case Study: A European power plant upgraded its legacy relay system with the IS200TRLYH1B, reducing downtime by 20% and cutting maintenance costs by $80,000 annually 5. The module’s fast response time (25ms) and surge protection minimized equipment damage during voltage fluctuations.
5. Competitor Comparison
The IS200TRLYH1B outperforms generic relay modules with its deep integration into GE’s Mark VI ecosystem, offering turbine-specific algorithms and faster data processing. Its wide temperature range (-20°C to 60°C) and surge protection exceed standard industrial modules, while its modular design allows for quick field upgrades without full system reconfiguration 9.
