Description
Product Overview
The GE DS200TCEAG1A is an emergency overspeed protection board designed for GE’s Speedtronic Mark V turbine control systems. It functions as a critical safety component, monitoring turbine speed and flame detection signals to prevent catastrophic failures in industrial gas/steam turbines. Equipped with an Intel 80196 microprocessor and multiple programmable PROM modules, this module executes real-time diagnostics and triggers emergency shutdowns (e.g., fuel cutoff) within milliseconds when speed thresholds are exceeded. Its integration into GE’s Mark V platform ensures compatibility with legacy and modern control architectures, providing SIL 3-compliant safety for power generation and heavy industrial applications. The DS200TCEAG1A enhances system resilience against electrical surges and mechanical stress, making it indispensable for mission-critical environments like power plants and offshore oil platforms.

Main Features and Advantages
Ultra-Fast Safety Response:
The DS200TCEAG1A detects turbine overspeed deviations within milliseconds, activating shutdown protocols to prevent mechanical damage. Its TMR architecture ensures fault tolerance, maintaining operations even during single-point failures—critical for nuclear plants and offshore rigs where downtime is unacceptable.
Robust Environmental Adaptation:
Operating in -40°C to 70°C extremes with IP65-rated protection, the module resists dust, humidity, and vibration (5G RMS). Fanless magnesium alloy construction extends lifespan in corrosive environments like refineries and marine platforms.
Integrated Diagnostics and Cybersecurity:
Onboard LEDs provide real-time status alerts for power and faults, while embedded AES-256 encryption and secure boot firmware defend against cyber threats. Compatibility with GE’s EnerVista software enables predictive maintenance, reducing unplanned downtime by 40%.
Compact and Modular Design:
Weighing 4.3 kg with DIN-rail mounting, the board simplifies retrofits in space-constrained panels. Hot-swappable components allow maintenance without system shutdowns.
Application Areas
- Power Generation: Safeguards gas/steam turbines from overspeed-induced failures, ensuring grid stability during load fluctuations. Deployed in plants for real-time monitoring of pressure, temperature, and emergency shutdowns (ESD).
- Oil & Gas: Protects compressor drives and drilling rig SCADA networks with ATEX/IECEx compliance for explosive atmospheres. Monitors pipeline flow rates to prevent overloads.
- Industrial Automation: Enforces safety in pharmaceutical batch processes and robotic assembly lines via GMP/FDA-compliant data logging and shutdown triggers.
