GE DS200TCTGG1AFF Trip Board – Mark V Turbine Control System
1. Primary Function
The DS200TCTGG1AFF is a Trip Board (also referred to as a Simplex Trip Board) designed for GE’s Speedtronic™ Mark V turbine control system.
It serves as a critical safety module, responsible for monitoring turbine operating parameters and initiating emergency shutdowns when unsafe conditions are detected.
2. Key Roles & Features
A. Safety Monitoring & Trip Activation
Continuously monitors turbine operational parameters (e.g., speed, vibration, temperature, pressure).
Triggers an emergency shutdown (trip) if any parameter exceeds predefined safety limits to prevent equipment damage.
B. Relay Output Control
Equipped with multiple relay output channels to control external devices (e.g., valves, motors, alarms) during trip events.
Supports hardwired safety circuits for fail-safe operation.
C. Modular & Robust Design
Modular construction allows for easy replacement or expansion of relay channels.
Engineered for high reliability in harsh industrial environments (e.g., power plants, oil/gas facilities).
D. Diagnostic & Maintenance
LED indicators (if equipped) provide real-time status of trip conditions and relay operations.
Requires proper power cycling during installation/removal to avoid damage (must de-energize equipment before handling).
3. Typical Applications
Gas/steam turbine protection: Ensures safe shutdown during overspeed, excessive vibration, or overheating.
Industrial safety systems: Integrates with DCS/PLC for coordinated emergency responses.
