GE DS200SIOBH1A SC2000 VME I/O Board

الوصف

The GE DS200SIOBH1A is a specific revision of the SC2000 VME I/O Board (SIOB), primarily utilized in the GE Mark V Speedtronic Turbine Control System and related drive systems (¹$\text{SC}2000$ or ²$\text{UC}200\text{V}$).³

It serves as an auxiliary $\text{I/O}$ expansion module that mounts in the $\text{VME}$ rack to increase the system’s capacity for monitoring and control of field devices.

Key Features and Function

System Role

The SIOB is essential when a turbine or drive control application requires more input/output points than the main controller modules can provide. It interfaces directly with the central processing units via the $\text{VME}$ bus.

Hardware and Configuration

• Form Factor: It is a ⁴$\text{VME}$ standard board, plugging into a single ⁵$\text{VME}$ rack slot and connecting to the ⁶$\text{VME}$ ⁷$\text{P1}$ connector.⁸ It supports $\text{16-bit}$ data transfers.

   

• Connectivity: The faceplate provides ⁹$\text{I/O}$ connectors (typically ¹⁰$\text{J1}$ and ¹¹$\text{J2}$) that link via ribbon cables to external terminal boards (¹²$\text{TBA}/\text{TBB}$), where field wiring for sensors and actuators is terminated.¹³

   

• Adjustments: It is equipped with:
  • Three Switch Blocks (18 switches total) for setting board addresses or operating modes.¹⁴

     

  • Approximately 20 Configurable Jumpers for parameter tuning (e.g., scaling or test functions).¹⁵

     

• Diagnostic: A single ¹⁶$\text{LED}$ on the faceplate illuminates when the board is being accessed by the ¹⁷$\text{VME}$ system, indicating communication status.¹⁸

   

• Coating: The “$\text{H}$” in the part number indicates a conformal coating applied to the printed circuit board, which provides protection against moisture, dust, and chemicals commonly found in industrial environments.
