GE IS200CTBCG1A Mark VI I/O Terminal Board

الوصف

The GE IS200CTBCG1A is an I/O Terminal Board manufactured by General Electric (GE) for the Mark VI Speedtronic Turbine Control System.

It is a critical interface board, often designated by the acronym CTBC, that serves as the connection point between the control system’s internal electronics and the external field wiring.

⚙️ Core Function and Role

The primary function of the IS200CTBCG1A is to provide a robust, centralized, and secure connection for Input/Output (I/O) signals between the turbine’s sensors/actuators and the Mark VI control modules.

• Customer Wiring Interface: It is the main point where customer wiring (the wires coming from the turbine’s field devices) terminates. This simplifies cable management and maintenance.
• Signal Distribution: The terminal board distributes (fans out) the incoming signals to the appropriate I/O boards within the Mark VI rack, which are responsible for processing the signals.
• Protection Circuitry: Like most Mark VI terminal boards, the CTBC contains minimal active circuitry to enhance reliability and reduce potential single points of failure. The active components are typically limited to filters and protective devices to shield the control system from electrical surges and high-frequency noise.
• System Context: This board is an integral part of the overall Mark VI control architecture, enhancing its capability to manage signals from various sensors and actuators to ensure precise control and monitoring of the industrial gas or steam turbine.
