GE IS200EXTBG1AAA EX2100 Terminal Board

د.إ8,888.00

GE IS200EXTBG1AAA is the EX2100 Terminal Board (EXTB), a key component in the GE EX2100 Excitation Control System for large synchronous generators.

Its primary function is to serve as the main, high-density interface point for external field wiring, allowing signals and power to be connected to the internal control electronics safely and reliably.

⚙️ Core Functions and Role

The EXTB board acts as the bridge between the field wiring in the generator and the sensitive control electronics (like the EX2100’s various I/O and communication boards).

  • Wiring Termination: The board features numerous high-density terminal blocks where all incoming and outgoing control, protective, and sensing wires are connected. This includes signals for:
    • Exciter Field Voltage/Current: Sensing wires for monitoring and control.
    • Generator Protection: Wires for differential protection, over-excitation limits, and other safety functions.
    • External Communications: Signals from other devices or control systems.
  • Isolation and Buffering: While primarily a terminal board, it often includes basic conditioning and isolation circuitry to protect the internal electronics from transient voltages or noise carried over the long field cables.
  • Signal Distribution: It routes the terminated signals to the appropriate internal circuit boards within the EX2100 cabinet, usually via ribbon cables or backplane connections.

🛠️ Technical Details (IS200EXTBG1AAA)

  • System: EX2100 Excitation Control System.
  • Location: Typically mounted on the back wall of the EX2100 cabinet (often called the Auxiliary Cabinet).
  • G1AAA Suffix: This denotes the specific revision of the terminal board. The G1 variant is the standard configuration for the terminal board used in most EX2100 systems, supporting both simplex and redundant (TMR) architectures.

The reliability of the EXTB is critical, as it ensures all necessary control and feedback signals—essential for stable voltage regulation and generator protection—are correctly and securely connected to the system.
