Description
1. Product Description
The DS200TCTSG1AFE is a simplex trip board engineered by General Electric (GE) for its Mark V turbine control systems. This model, the DS200TCTSG1AFE, serves as a critical safety component in high-voltage drive applications, delivering precise emergency tripping and protective relay functions. Its primary role is to manage turbine overspeed protection, auxiliary solenoid control, and redundant signal processing, ensuring compliance with safety standards in power generation and industrial settings.
Key features of the DS200TCTSG1AFE include 12 plug-in relays, 3×16-pin connectors (JDR, JDS, JDT), and 2×12-pin connectors (JN, JM) for modular connectivity. It supports artwork revision E (enhanced durability) and functional revisions A/F (subtle performance optimizations), making it compatible with GE’s evolving control architectures.
