Description

The GE IS200TBCIS2CCD is a specialized Termination Board Assembly designed for the Mark VI and Mark Vie series turbine control systems. This module does not perform active signal processing or control logic; instead, it serves as the critical passive interface between the field wiring from sensors and actuators and the active electronic I/O modules within the control rack. The primary function of the IS200TBCIS2CCD is to provide the physical termination points—typically screw terminals or connectors—for the hundreds of wires coming from the field devices on the turbine. It organizes these connections, provides necessary signal conditioning components like resistors or fuses in a centralized location, and routes the signals via internal ribbon cables to the appropriate analog or digital input/output modules.

As an integral part of the Speedtronic platform’s I/O subsystem, the IS200TBCIS2CCD is engineered for robustness and reliability. Its design simplifies the wiring process, reduces installation errors, and enhances maintainability by providing a clear and organized interface point. By centralizing terminations, it protects the more sensitive active electronics from the potential hazards of field wiring, such as accidental shorts or miswiring during maintenance. The GE IS200TBCIS2CCD is a foundational component that ensures the integrity of the signal path between the turbine’s physical processes and the digital control system, contributing significantly to the overall stability and availability of the turbine unit.

Main Features and Advantages

The GE IS200TBCIS2CCD offers significant advantages in system organization and serviceability. A primary feature is its role in simplifying the complex wiring infrastructure of a turbine control system. By providing a clearly labeled and structured terminal block, it drastically reduces the time and potential for error during initial installation and subsequent troubleshooting. This organized approach allows technicians to quickly identify and isolate field circuits without disturbing the wiring to the active electronic modules, which minimizes downtime during maintenance activities. The robust screw terminals ensure a gas-tight connection, preventing loosening due to vibration, a common issue in power plant environments.

Enhanced system protection and modularity are key benefits of this termination board. The IS200TBCIS2CCD often incorporates protective components such as fuses or surge suppressors on its board, which help shield the expensive active I/O modules from damage caused by overcurrents or voltage transients on field wiring. This design philosophy localizes potential damage to a easily replaceable, low-cost termination board rather than a complex signal processing module. The modular nature of the IS200TBCIS2CCD means it can be quickly swapped out if damaged, further enhancing system availability. Its passive design ensures inherent reliability, with no firmware or software to configure, making it a simple yet vital component for system integrity.

Application Field

The application of the GE IS200TBCIS2CCD is specific to environments utilizing the GE Mark VI or Mark Vie control systems, primarily in power generation. It is used across the entire spectrum of turbine control, interfacing with field devices for both gas and steam turbines. In a typical application, the IS200TBCIS2CCD would be the termination point for wiring from critical sensors such as thermocouples, RTDs, pressure transmitters, and vibration probes. Conversely, it also provides the termination points for output signals traveling to final control elements like servo valves, solenoid valves, and motor starters.

This board is essential in the organized marshalling of I/O signals within the control cabinet. For example, in a gas turbine application, one IS200TBCIS2CCD might be dedicated to terminating all wiring associated with the combustion monitoring system, while another handles lube oil system inputs and outputs. This logical grouping by system function, facilitated by the termination board, greatly simplifies circuit tracing and system understanding for maintenance personnel. The IS200TBCIS2CCD is therefore a ubiquitous component in the control cabinets of combined-cycle power plants, simple-cycle peaker plants, and industrial turbine installations worldwide, forming the backbone of the physical I/O interface.
