DS200CTBAG1A-BD | GE Mark V Analog Termination Board

The DS200CTBAG1A-BD is an Analog Termination Board (CTBA) designed for use in the GE Mark V Speedtronic Turbine Control System. This module plays a critical role in the system by acting as a termination point for various analog signals. It supports the processing and routing of signals between the turbine control system’s components, enabling efficient management and monitoring of turbine operations.

Key Features

Signal Termination and Routing:
- Handles the termination of analog signals, such as mA inputs and outputs.
- Facilitates communication between key modules, including IONET and ARCNET processors.
System Integration:
- Installed within the C Core of the Mark V system.
- Interfaces with other boards and modules through multiple connectors, ensuring seamless signal flow.
Diagnostics Support:
- Equipped with an RS-232 9-pin serial port for TIMN diagnostics, enabling efficient troubleshooting and maintenance.
Hardware Jumpers:
- Features configurable jumpers (BJ1-BJ15) to customize signal routing:
  - BJ1-BJ14: Connect the NEG input of mA signals to DCOM.
  - BJ15: Links the RS-232 Monitor Port to DCOM.
Electrical Components:
- Includes resistors, capacitors, varistors, and diodes for signal protection and voltage suppression.
Legacy Component:
- Part of the GE Mark V series, which is considered a legacy system due to its discontinuation. Replacement parts and spares are still available through specialized suppliers.
