Description
Product Overview
The GE DS200TCTGG1ABA is a Turbine Control Trip Board engineered for GE’s Mark V Speedtronic turbine control system, serving as a critical safety component in steam turbine automation. Belonging to the legacy DS200 series, this module is designed to execute emergency shutdowns, overspeed protection, and diagnostic testing in mission-critical industrial environments, including power generation, oil & gas, and heavy manufacturing.
As the master trip circuit within the Mark V system, the GE DS200TCTGG1ABA monitors turbine speed and triggers protective shutdowns when parameters like vibration or temperature exceed safe thresholds. It features dual primary trip relays (PTR1 & PTR2) and three emergency trip relays (ETR1–ETR3), ensuring redundant activation of safety measures. The module also includes auxiliary control outputs for solenoid valves, enabling comprehensive testing of oil pressure, mechanical lockout, and overspeed trip mechanisms. Its triple modular redundancy (TMR) architecture ensures continuous operation even if one channel fails, making it indispensable for systems where downtime is costly.

Main Features and Advantages
High-Reliability Safety Architecture:
The TMR design of the GE DS200TCTGG1ABA ensures fault tolerance by maintaining operation across three independent channels, the failure of one channel does not compromise system integrity. This is critical for preventing catastrophic turbine failures in power plants and offshore platforms. The module’s PCB coating resists dust, moisture, and electromagnetic interference, enhancing durability in harsh industrial settings.
