GE DS200SIOBH1 VME Stand I/O Card

الوصف

The GE DS200SIOBH1 is a VME Stand I/O Card (SIOB), which stands for SC2000 VME I/O Board, primarily used in the GE Mark V Speedtronic Turbine Control System and its associated drive systems ($\text{SC}2000$ or $\text{UC}200\text{V}$).

This board functions as an auxiliary $\text{I/O}$ expansion module, allowing the main turbine or drive controller to interface with a larger number of field sensors, actuators, and devices than the standard system provides.

Key Features and Functionality

1. System Role and Architecture

• Purpose: To expand the Input/Output capabilities of the control system, managing additional digital and/or analog signals.
• VME Compatibility: It is a $\text{VME}$ board, meaning it mounts directly into a $\text{VME}$ rack slot and connects to the $\text{VME}$ P1 connector. It supports standard $\text{VME}$ addressing and $\text{16-bit}$ data transfers.
• System Integration: It is categorized as an auxiliary module, often used in conjunction with $\text{UC}200\text{V}$ systems to meet specific application $\text{I/O}$ requirements.

2. Onboard Components and Configuration

The board is highly configurable to match the specific application requirements:

• Switch Blocks: It features three switch blocks, each typically containing six switches, totaling 18 switches. These are used to set board addresses, configuration parameters, and operating modes.
• Jumpers: It includes approximately 20 configurable jumpers for making various hardware selections, such as signal type, scaling, or test modes.
• Diagnostic $\text{LED}$: A single $\text{LED}$ on the faceplate lights up when the board is actively accessed by the $\text{VME}$ bus, indicating normal communication.
• Connectors: It usually has two $\text{I/O}$ connectors ($\text{J1}$ and $\text{J2}$) that connect via ribbon cables to external terminal boards ($\text{TBA}/\text{TBB}$) for wiring field devices.
