GE DS200TCEBG1ABC Protective Termination Expander Board

د.إ8,888.00

GE DS200TCEBG1ABC Protective Termination Expander Board (TCEB) is a specific revision of a key interface card within the General Electric Mark V Speedtronic Turbine Control System.1

 

The alphanumeric suffix G1ABC indicates the specific revision of the board, which often includes minor changes to component layout or functionality compared to the base DS200TCEBG1. Its core function, however, remains consistent across the TCEB line.

 

🚀 Core Functionality

 

The TCEB board is an essential part of the turbine’s core control system, providing signal conditioning, routing, and a physical interface for critical safety and measurement signals.2

 

  • Signal Conditioning/Scaling: It’s an expander card that conditions and scales signals from the Potential Transformers (PT) and Current Transformers (CT).3 These conditioned signals are crucial for measuring generator and bus voltages and line current, and are then sent to the TCCB (Turbine Core Control Board).4

  • Protection Signal Routing: It routes key safety signals, such as emergency overspeed magnetic pick-up and flame detection signals.5 These signals come from the PTBA terminal board and are passed through the TCEB to the TCEA (Emergency Overspeed) boards for processing in the redundant Mark V system.6

     

  • Flame Detector Power: It conditions and routes the 335 V DC power required for the Ultra Violet (UV) flame detector devices.7

     

  • Audible Alarm: The board holds the audible alarm horn for the Mark V LM system, providing a local alert for critical conditions.8

     

 

📋 Technical Overview

 

Feature Detail
System Series GE Mark V Speedtronic Turbine Control System (DS200 Series)
Product Type Protective Termination Expander Board (TCEB), also a Common Circuits EOS Board
Typical Location Located in the P1 core of the Mark V system chassis
Connectors Features a variety of connectors for interfacing with other boards (e.g., TCCB, PTBA, TCEA), including: 3 Bayonet Connectors, 4 Signal Transformers, 3 x 20-pin Ribbon Cable Connectors (JKX, JKY, JKZ), 1 x 26-pin connector, and 4 x 10-pin connectors.
PT/CT Signals Carried via connectors like JMP (to TCCB) and JV (from PTBA).
Overspeed/Flame Detect Carried via connectors like JU (from PTBA) and JKX/Y/Z (to TCEA boards).

This specific board is critical to the Mark V system’s fault-tolerant architecture by ensuring the integrity and proper routing of signals essential for both control and emergency protection of the turbine.9
