GE IS200TRLYH1BGF Product Description
The GE IS200TRLYH1BGF is a Relay Output Board developed by General Electric (GE) as a key component of the GE Mark VI Turbine Control System, GE’s advanced control system designed for gas/steam turbine management to provide a smooth transition from zero speed to operating speed. The Mark VI system is an advanced control system designed by GE for gas/steam turbine management to provide a smooth transition from zero speed to operating speed and to ensure smooth acceleration of the turbine through automated control signal sequences, particularly acceleration control.
The IS200TRLYH1BGF, as part of the Mark VI system, is primarily responsible for converting control system commands into the electrical signals required to drive field actuators such as solenoid valves, contactors, circuit breakers, and so on. It is capable of handling complex logic and providing safe shutdown functions when required to ensure safe and reliable operation of the turbine and associated equipment.
Main Functions
The core functionality of the GE IS200TRLYH1BGF centers around its relay output and signal processing capabilities:
Relay Output Control: Includes up to 12 plug-in magnetic relays, providing flexible configurations to suit a variety of applications. It is capable of converting digital or logic signals from the controller into high-power switching outputs for direct control of field devices.
Versatile Output Options: The first six relay circuits can be configured with jumpers to select dry, Form-C outputs or to drive external solenoid valves, adding flexibility to system design.
Multiple power supply support: A variety of power supply options are supported, including standard 125 V DC or 115/230 V AC, and an optional 24 V DC power supply. Each power supply is equipped with individual jumper-selectable fuses and on-board suppression for added safety and reliability.
Safety Protection: Safety features such as built-in on-board load suppression and individual jumper-selectable fuses ensure safe and reliable operation. It also features fault detection mechanisms, such as detecting loss of relay coil excitation current and triggering an alarm to notify the operator.
Redundancy Support (TMR): In some configurations (e.g. with VGEN, VCRC or VCCC boards), it can support Triple Modular Redundancy (TMR) configurations, which increase system availability and fault tolerance by voting signals from three separate control channels, ensuring safe operation in the event of a single point of failure.
Status Indication and Diagnostics: LEDs are typically provided to indicate module operational status, relay status and potential faults for easy field diagnostics and maintenance.
Seamless Integration with Control Systems: Designed for seamless integration with GE Mark VI control systems to ensure efficient transmission of control signals and data exchange.
Product Applications
The GE IS200TRLYH1BGF is primarily used in industrial applications where reliability, safety and performance are paramount, especially those involving large rotating machinery, including:
Power Generation: Widely used in thermal power plants, combined cycle power plants, etc. It is used in the control system of gas turbine and steam turbine, controlling key equipment such as start/stop sequences, fuel valves, steam valves, and generator circuit breakers.
Oil & Gas: Used in refineries, gas processing plants and pipeline compressor stations to control the safety and operation of gas turbine driven compressors and pumps.
Petrochemical Industry: For the control of turbomachinery in large industrial processes to ensure the stability and safety of the production process.
Other industrial automation: Any industrial automation application requiring highly reliable relay outputs and complex control logic.
