  • Placement: The DS200DTBBG1A is typically located in the Mark V system’s QD or C cores, placing the I/O close to the field wiring and minimizing the distance between the control system and the turbine’s digital sensors. This strategic placement helps ensure efficient signal transmission and reduces the risk of interference or signal degradation.
  • Obsolete Status: As a component of the discontinued Mark V series, the DS200DTBBG1A is considered an obsolete part. It is no longer manufactured by GE and is typically sourced from new old stock, surplus vendors, or specialized repair and refurbishment companies.

الوصف

The GE DS200DTBBG1A is a specialized circuit board known as a Terminal Digital Connector Card for the Mark V series of turbine control systems. It is not a modern PLC module but an obsolete printed circuit board (PCB) that acts as an interface for digital inputs.

 

Key Features and Function

 

  • Digital Contact Input Terminal Board: Its primary function is to terminate the wiring for a large number of digital contact inputs from various field devices (e.g., switches, limit switches, and sensors). The board is designed to provide a high-density, easily serviceable I/O interface.
  • High-Density I/O: The board features two terminal blocks, each with terminals for up to 95 signal wires, for a total of 190 terminals. This high density allows for the termination of a significant number of inputs in a compact space.
  • Mark V Series: This board is a component of the GE Speedtronic Mark V series, a legacy control system widely used in the power generation industry for controlling gas, steam, and wind turbines. The system is known for its high reliability and triple-redundant processors for critical functions.
  • Connectivity: The board includes three 50-pin connectors with bayonet-style connectors, making it easy to connect and disconnect ribbon cables to the main controller. It also has five jumpers and a set of IDs for the terminal blocks and connectors to help with proper wiring and troubleshooting.
  • Placement: The DS200DTBBG1A is typically located in the Mark V system’s QD or C cores, placing the I/O close to the field wiring and minimizing the distance between the control system and the turbine’s digital sensors. This strategic placement helps ensure efficient signal transmission and reduces the risk of interference or signal degradation.
  • Obsolete Status: As a component of the discontinued Mark V series, the DS200DTBBG1A is considered an obsolete part. It is no longer manufactured by GE and is typically sourced from new old stock, surplus vendors, or specialized repair and refurbishment companies.
