GE DS200TCTEG1A TC2000 Trip Module

الوصف

The GE DS200TCTEG1A TC2000 Trip Module is a critical circuit board used in the General Electric Speedtronic Mark V Turbine Control System.¹

Its core purpose is to provide essential trip and protection functionality for the gas or steam turbine, ensuring a safe and rapid shutdown (a “trip”) when critical operational limits are violated.²

⚙️ Function and Role in Mark V

Primary Function: Safety and Protection

The DS200TCTEG1A, also known by its functional acronym TCTE, acts as a safety processor within the Mark V control system.³

• Trip Logic Processing: It processes inputs related to various protective conditions, such as overspeed, high vibration, low lube oil pressure, or other critical alarms.⁴
• Trip Initiation: It is integral to the logic that initiates the emergency shutdown sequence, swiftly closing fuel or steam stop valves to protect the turbine from damage.⁵
• Component of Trip System: It works in conjunction with other trip-related boards in the Mark V system, such as the $\text{DS200TCTGG1A}$ (TCTG) and $\text{DS200TCEAG1A}$ (TCEA – Emergency Overspeed Board), to form the complete, redundant safety architecture.

System Location and Series

• Series: It is a component of the DS200 series circuit boards for the GE Speedtronic Mark V Turbine Control System.
• Redundancy: The Mark V system often uses a Triple Modular Redundancy (TMR) architecture (R, S, T controllers) for control and protection, and the TCTE is one of the boards supporting this safety philosophy.⁶
• TC2000: The “TC2000” designation indicates it is a specific type of board architecture utilized within the Mark V control platform.
