IS200VAICH1DAA | GE | Mark VI Analog Input/Output Board

Product Overview

The GE IS200VAICH1DAA serves as a high-density Analog Input/Output (VAIC) Board designed for the General Electric Speedtronic Mark VI turbine control system. This module occupies a critical role in the VME rack, managing the interface between field sensors and the control processors. We supply this board as 100% Brand New and Original, ensuring your control architecture utilizes genuine General Electric Industrial Systems hardware. By integrating 20 input channels and 4 output channels, the IS200VAICH1DAA provides the necessary bandwidth for complex monitoring and closed-loop control tasks in power generation facilities.

Technical Specifications

The IS200VAICH1DAA utilizes advanced VMEbus architecture to provide high-speed data acquisition and precise signal modulation.

Engineering Advantages

• High-Density Input Processing: The module accommodates 20 analog inputs, allowing engineers to consolidate multiple sensor signals onto a single VME slot. This density optimizes rack space and simplifies backplane wiring in crowded control cabinets.

• Dual-Range Output Versatility: Unlike standard I/O boards, the IS200VAICH1DAA supports both 4-20 mA and 0-200 mA output circuits. The high-current 200 mA capability allows the board to drive specialized actuators and heavy-duty field devices directly without requiring external boosters.

• Seamless VME Rack Integration: Specifically designed for the Mark VI VMEbus, this board slides directly into the control rack. The hardware identifies itself to the system automatically, facilitating rapid communication with the controller and reducing downtime during hardware refreshes.

• Precision Signal Conditioning: The VAIC board utilizes high-grade filtering to eliminate electrical noise from field wiring. This ensures that the 20 analog inputs deliver a clean, accurate representation of turbine health to the central processing unit.

• USA-Engineered Reliability: Manufactured by GE Industrial Systems in the USA, the board adheres to strict quality standards. The "DAA" revision incorporates optimized circuit layouts that improve thermal management compared to early-generation VAIC modules.

FAQs

• Can the IS200VAICH1DAA replace an older VAICH1A or VAICH1B board?

  Yes. The "DAA" suffix represents a later functional revision level that maintains full backward compatibility with earlier VAICH1 variants. It functions as a direct drop-in replacement within the Mark VI VME rack.

• How does the board handle the 0-200 mA high-current output?

  The board features specialized output circuitry designed to manage the increased thermal load of 200 mA signals. You must ensure the field wiring meets the current-carrying capacity requirements specified in the GEH-6421 manual.

• Is software configuration required after installation?

  While the hardware is "plug-and-play" in the VME rack, you must use the Mark VI Toolbox software to map the I/O points and configure the specific signal types (voltage or current) for the 20 input channels.

• How do I confirm this unit is "Brand New"?

  We deliver every IS200VAICH1DAA in its original factory-sealed packaging. The PCB displays an authentic GE serial number and the functional revision "DAA" stamping, ensuring the unit has never seen field service.
