GE IS205SVMAG2A

¥999.00

The GE IS205SVMAG2A is a VMEbus terminal board manufactured by General Electric for the Mark VIe distributed control system (DCS). This board is a high-performance Servo Valve Monitoring and Actuation Gateway module, representing a significant upgrade over the SVMAG1A series. The GE IS205SVMAG2A provides high-precision monitoring, diagnostic, and actuation control for servo and proportional valves in turbine control applications, with higher channel density, improved accuracy, faster response, and expanded diagnostics. The “H2A” designation indicates a second-generation servo valve monitoring and actuation module designed for demanding turbine control applications requiring maximum precision and reliability.

Selection Guidelines

  • When to choose: Applications requiring high-density servo valve control with comprehensive monitoring (up to 8 valves per module).

  • Output Configuration: Select 4–20 mA for most servo valves; ±20 mA for high-noise environments; ±10 V for valves with local amplifiers.

  • Monitoring Configuration: Configure feedback inputs for LVDT/RVDT; configure process inputs for pressure/temperature.

  • Compatibility: Fits all Mark VIe VME64x racks. Requires ControlST v6.5 or higher.

Operational Precautions

  1. Wiring: Follow GE wiring diagrams—correct polarity and shield grounding essential.

  2. Feedback Polarity: Verify feedback sensor polarity in Toolbox ST.

  3. Calibration: Factory calibrated—verify output against known reference during commissioning.

  4. Valve Performance Monitoring: Review performance metrics periodically for predictive maintenance.

  5. LED Diagnostics: Green = normal; Amber = fault/marginal; Red = module fault.

  6. Fault Log: Access 750-event log via Toolbox ST.

  7. Coating Care: Use GE-approved cleaner; inspect annually under UV.

  8. Hot-Swap: Remove/insert slowly under power.

  9. Spare Stock: Maintain 1 spare per 3–4 racks.

  10. Firmware Updates: Ensure the GE IS205SVMAG2A is in “standby” mode.

  11. ESD: Handle by edges with grounded wrist strap.

  12. Storage: Anti-static bag with desiccant at –40 to +85 °C.
