GE DS200TBSAG1 Serial Communication Termination Module

الوصف

The GE DS200TBSAG1 is a Serial Communication Termination Module (Functional Abbreviation: TBSA) designed for use within the General Electric Speedtronic Mark V Gas/Steam Turbine Control System.¹

💻 Primary Function and Application

The main function of the DS200TBSAG1 board is to provide the physical termination and signal integrity for serial communication links within the Mark V control panel.²

1. Serial Communication Interface

• Role: It is the interface board that receives and terminates serial communication wiring from field devices or other control system components.
• Application: It is primarily used to handle the serial links, particularly for the FMVED (Fuel Manifold Valve Electronic Driver) motor controller serial links, which are crucial for controlling the precise position of fuel valves in the gas turbine system.³

   

• Signal Integrity: Proper termination is vital in serial communication (like $\text{RS-485}$ or similar standards) to prevent signal reflections that can cause data corruption and communication failure, ensuring reliable control of the turbine.

2. Turbine Control System Context

• System: It’s part of the DS200 series of printed circuit boards, all of which belong to the GE Mark V Speedtronic control system.⁴

   

• Location: The board is typically installed in one of the I/O cores of the Mark V panel, such as location 8 of the ⁵$\text{R2}$ core.⁶

   

• Configuration: The board includes a series of manually-moveable hardware jumpers (e.g., ⁷$\text{JP1}$ to ⁸$\text{JP16}$) that allow for the configuration of various communication circuits, often related to the reception and transmittal of the serial signals.⁹

   

🔩 Key Specifications

As the Mark V is a legacy control system, this board is usually sourced as a rebuilt, unused surplus, or repaired component from third-party industrial automation suppliers.¹⁰
