The GE IS200TRLYH1BHH / IS200TRLYH1B Mark VIe Relay Output Terminal Board is a critical component in General Electric’s Mark VIe gas/steam turbine control system.
Here’s its primary role and functions in English:
1. Function & Purpose
Relay Output Interface: Acts as an intermediary between the Mark VIe controller’s low-voltage logic signals and higher-power field devices (e.g., solenoids, motors, alarms).
Signal Isolation: Provides electrical isolation between the sensitive control system and external high-voltage/current circuits to prevent interference or damage.
Termination Point: Serves as a wiring hub for connecting relay outputs to external equipment, simplifying maintenance and troubleshooting.
Redundancy Support: In critical applications, it may facilitate redundant relay configurations for fail-safe operation.
2. Key Features
Compatibility: Designed for GE’s Mark VIe platform, integrating with I/O packs (e.g., IS200ERLYH1B).
Relay Control: Typically includes electromechanical or solid-state relays to switch loads.
LED Indicators: Visual status feedback (e.g., relay activation, faults).
Modular Design: Hot-swappable in some configurations to minimize downtime.
3. Typical Applications
Turbine protection systems (trips, alarms).
Actuator/solenoid control in power plants.
Industrial automation where relay-based output is required.
