IS200VAICH1CBA | General Electric | Mark VI Analog Input/Output Board

Product Overview

The IS200VAICH1CBA functions as a high-density Analog Input/Output (VAIC) board within the General Electric Mark VI Speedtronic control ecosystem. This 100% Brand New original component manages up to 24 channels of high-resolution analog data, providing the essential interface between field sensors and the central turbine controller. It utilizes an onboard Intel Celeron processor to execute local signal conditioning and diagnostic routines, ensuring the Mark VI governor receives precise, real-time data for fuel control, temperature monitoring, and valve positioning.

Technical Specifications

The IS200VAICH1CBA integrates high-speed processing with precision conversion hardware to maintain signal integrity in utility-scale power environments.

Engineering Advantages

• Ultra-High Resolution Acquisition: A 16-bit A/D converter ensures maximum precision when digitizing 4-20 mA field signals. This high granularity allows the control system to detect minute process variations, which significantly improves the stability of turbine combustion and emission control loops.

• Deterministic Local Processing: The onboard 300 MHz Intel Celeron processor manages all 24 channels independently of the main controller. This distributed architecture offloads the computational burden from the CPU rack and guarantees a consistent 10 ms scan time, providing the rapid response speeds required for emergency trip parameters.

• Slim-Profile Integration: The board measures only 1.99 cm in width. This narrow form factor maximizes rack density, allowing engineers to install more I/O capacity within existing Mark VI cabinets without requiring costly enclosure expansions.

• Robust Network Connectivity: Dual-speed Ethernet ports (10/100BaseTX) facilitate seamless data exchange across the IONet. This standardized RJ-45 interface simplifies the integration of the VAIC board into modern plant-wide monitoring networks while maintaining compatibility with legacy Mark VI hardware.

FAQs

• Is the IS200VAICH1CBA unit a brand new original?

  Yes. We supply this board exclusively as 100% Brand New original factory stock. Each unit arrives in its original anti-static shielding and includes the manufacturer’s identifying labels to guarantee field reliability and authenticity.

• Can this board handle both inputs and outputs simultaneously?

  The VAIC (Analog Input/Output) board manages 24 channels of input data while simultaneously providing analog outputs. The 16-bit input converter and 12-bit output converter operate in parallel to ensure synchronized control of field actuators and feedback sensors.

• How do I verify software compatibility for the "CBA" revision?

  The CBA suffix indicates a specific hardware revision. You must verify that your Mark VI configuration software (GEH-6421M manual) recognizes this revision level. Typically, the system firmware automatically detects the board ID and initializes the appropriate driver during the boot sequence.

• Does this board require specific cooling in a turbine control room?

  The IS200VAICH1CBA operates efficiently between 0 and 60°C. While it utilizes low-power components, you must maintain adequate airflow within the Mark VI rack to prevent heat accumulation, especially when stacking multiple high-density I/O boards.
