GE DS200TCEBG1A Protective Termination Expander Board

د.إ8,888.00

 

Characteristic Specification/Detail
System GE Speedtronic Mark V Turbine Control System
Product Type Protective Termination Expander Board (TCEB)
Location Typically installed in the P1 Core location of the Mark V panel.
Connectors Features a variety of connectors including bayonet connectors (JWX, JWY, JWZ), ribbon cable connectors (JKX, JKY, JXZ), and others (JMP, JV, JU, JVA) for signal transfer.
Configuration The TCEB itself typically has no software or hardware jumpers for configuration, as it is primarily a signal expansion and conditioning interface.

The DS200TCEBG1A is functionally interchangeable with later revisions (like DS200TCEBG1BAA) within the same Mark V system, though you should always refer to the specific GE documentation for compatibility before replacement.

الوصف

The GE DS200TCEBG1A is a revision of the Protective Termination Expander Board (TCEB), a crucial component in the General Electric Speedtronic Mark V Turbine Control System.1

 

The primary function of the TCEB is to condition, scale, and route critical protective and measurement signals between the terminal boards and the main processor boards in the protective core (2$P1$) of the control panel.3 The final letter, ‘A’, indicates the functional revision level of the original DS200TCEBG1 board.4

 

 

⚙️ Key Functions

 

The DS200TCEBG1A board is a common circuit card responsible for handling the most vital safety and electrical signals:5

 

 

1. Protective Signal Routing

 

The board routes high-speed signals for immediate protective actions:

  • It receives emergency overspeed (from magnetic pickups) and flame detection signals from the PTBA Terminal Board.6

     

  • It then routes these signals to the triple redundant TCEA (Emergency Overspeed Boards) for processing and trip-logic voting, which is the core of the Mark V’s protective system.7

     

 

2. Voltage and Current Signal Scaling

 

It acts as a conditioning and scaling interface for electrical measurements:8

 

  • It receives signals from the Current Transformers (CTs) and Potential Transformers (PTs), which represent line current, generator voltage, and bus voltage.9

     

  • It scales (converts) these signals to levels usable by the main TCCB (Turbine Control Core Board) in the control core (10$R5$) for monitoring and control logic.11

     

 

3. Alarm and Auxiliary Power

 

  • Alarm Horn: The board for the Mark V LM version often houses the audible alarm horn.12

     

  • Flame Detector Power: It processes and routes the 335 V DC power required for the Ultraviolet (UV) flame detector devices.13
