The GE part number IS200ECTBG2A is an EX2100 Contact Terminal Board. It is a component of GE’s Mark VIe Excitation Control System. Its primary function is to serve as a wiring interface for discrete contact inputs and outputs, providing a secure and organized connection point for the system’s digital signals. 🔌
Function and Key Features
A contact terminal board simplifies the complex task of wiring numerous on/off signals in a power plant. The “ECTB” in the part number stands for Excitation Contact Terminal Board.
- Wiring Interface: The board provides screw terminals where technicians can connect the field wiring from various contact input devices (e.g., limit switches, pressure switches) and to contact output devices (e.g., relays, solenoids).
- Signal Management: It handles the various types of digital signals, which can be either wet (powered by an external source) or dry (simple relay contacts). It may include noise suppression and filtering to ensure the integrity of the on/off signals.
- System Integration: The ECTB board plugs directly into a main control board in the EX2100 system. It’s a passive board that facilitates the flow of signals between the active electronics and the field devices.
- Robust Design: Like all GE industrial control components, it’s built to withstand the harsh conditions of a power plant.
Applications
The IS200ECTBG2A is a key component in power generation facilities that operate the EX2100 Excitation Control System. It is an essential component for:
- Safety and Interlocks: It is used to monitor the status of various safety devices and interlocks, ensuring that the generator and its auxiliary systems are in the correct state for safe operation.
- Status Monitoring: It provides the main controller with on/off status signals from various field devices, allowing for continuous monitoring of the system.
- Control of Auxiliary Equipment: It is used to control auxiliary equipment by providing digital outputs to activate relays, solenoids, or alarms.
