GE DS200SIOCG1A VME Stand I/O Board

الوصف

The GE DS200SIOCG1A is a specialized version of a VME Stand I/O Board designed for the GE Mark V Speedtronic Turbine Control System. Unlike the general-purpose $\text{SIOB}$ boards, this specific model is often categorized as an Instantaneous Overcurrent Board or VME Standard I/O Card that includes direct wiring terminals.

Its primary role is to serve as an I/O expansion module within the $\text{VME}$ rack, handling input/output signals and often providing a protection function, such as fast overcurrent detection, for critical equipment.

Key Features and Design

System and Function

• Application: Used in the GE Mark V Speedtronic Series for gas, steam, and wind turbine control systems, specifically within $\text{SC}2000$ or $\text{UC}200\text{V}$ subsystems.
• VME Compatibility: It is a $\text{VME}$ standard board that mounts in a single $\text{VME}$ rack slot and connects to the $\text{VME}$ $\text{P1}$ connector. It supports $\text{16-bit}$ data transfers.
• I/O and Protection: While it performs general $\text{I/O}$ functions, the $\text{DS}200\text{SIOCG1A}$ is frequently described as a card that:
  • Features instantaneous overcurrent protection to safeguard equipment by swiftly detecting and responding to current faults.
  • Provides standard $\text{I/O}$ for the control system.

Hardware Configuration

• Connections: This board is known to feature five wire terminal blocks ($\text{TB}-1$ to $\text{TB}-5$) that can connect a maximum of 33 signal wires directly to the board using screws, which is a key physical distinction from $\text{SIOB}$ boards that rely solely on ribbon cables.
• Components: It is populated with at least one fuse and multiple 2-pin connectors for signal interfacing.
• PCB Coating: The “G” in $\text{DS}200\text{SIOC}\mathbf{G}1\text{A}$ indicates it typically uses the Normal Style PCB coating, which provides basic protection, as opposed to the more extensive conformal coating found on “H”-designated boards.
