IS200TRLYH1BGF | GE Electric Triple C-type relay output module

IS200TRLYH1BGF | GE Electric Triple C-type relay output module

Product Description:

The IS200TRLYH1BGF is a Triple Form C Relay Output Module designed by GE for its Mark VI series Speedtronic gas/steam turbine control systems. Its primary function is to provide three independent, configurable, critical relay outputs based on commands from the Mark VI controller. Each relay channel typically controls a single high-power device (like a solenoid valve or trip coil) crucial for turbine protection, sequencing, or auxiliary operation. The module is engineered for high reliability in safety-critical applications.

Product Parameters / Specifications:

Series: This module belongs to GE’s Mark VI family of turbine control systems, the generation preceding Mark VIe. It operates within the Mark VI I/O architecture.

Key Features:

1. Triple Independent Relays: Three separate, high-reliability Form C relay outputs on a single module.
2. High Contact Rating: Capable of switching significant currents/voltages for critical loads like solenoids and trip coils.
3. High Voltage Isolation: Robust electrical isolation protects the sensitive control logic from high voltages/currents on the output side and prevents crosstalk.
4. Safety-Critical Design: Engineered for reliability in turbine protection and sequencing functions where failure is unacceptable.
5. Visual Status Indication: LEDs clearly show the active state (energized/de-energized) of each relay channel.
6. Dedicated Grounding: Separate lug ensures proper safety grounding of the module chassis.
7. Industrial Durability: Built to withstand harsh power plant environments (temperature, humidity, vibration, EMI).
8. Backplane Integration: Communicates seamlessly with the Mark VI controller via the VME backplane.

Function/Role: The IS200TRLYH1BGF acts as the final actuation point for critical control signals generated by the Mark VI controller. It translates low-power logic commands from the controller into high-power switching actions using its internal relays. This directly controls field devices essential for safe and efficient turbine operation.

Purpose/Use: This module is crucial for executing safety and control actions on the turbine and its auxiliary systems. Its typical uses include:

1. Turbine Protection: Actuating hydraulic trip solenoids to initiate an emergency shutdown (trip) when unsafe conditions are detected.
2. Valve Control: Operating solenoid valves for fuel, steam, air, or hydraulic systems based on control logic.
3. Auxiliary Equipment Control: Starting/stopping pumps, fans, or other auxiliary devices.
4. Alarm & Annunciation: Triggering external alarms or status indicators (e.g., horn, beacon).
5. Sequencing Logic: Performing discrete steps in startup, shutdown, or transfer sequences.

Application Fields / Industries:

• Power Generation (Primary Domain): 
  • Gas Turbine Power Plants
  • Steam Turbine Power Plants
  • Combined Cycle Power Plants (CCPP)
• Industrial Energy: Facilities using large GE turbine-generators for on-site power or cogeneration.
• Oil & Gas: Pipeline compressor stations driven by GE turbines controlled by Mark VI systems.
• Marine Propulsion: Naval or commercial vessels using GE gas turbines for propulsion (where Mark VI controls are applied).
• Heavy Industry: Plants with large turbine-driven mechanical drives (compressors, pumps) under Mark VI control.
• Test Facilities: Platforms for testing turbines and associated control systems.
