GE IS200VAICH1DAB – Vibration Analog Input Card | Mark VI Turbine Control Platform
Engineering Background: The IS200VAICH1DAB is a Vibration Analog Input Card (VAIC) designed and manufactured by GE as part of the Mark VI Turbine Control System — one of the most widely deployed distributed control architectures in gas turbine, steam turbine, and combined-cycle power generation facilities worldwide. This card serves as the primary interface for acquiring vibration and dynamic analog signals from turbine-mounted sensors, feeding real-time data into the Mark VI’s triple-redundant control loops.
Product Positioning: Targeted at maintenance engineers, OEM integrators, and procurement specialists managing GE Frame 6, Frame 7, and Frame 9 turbine fleets, the IS200VAICH1DAB provides a direct, form-fit-function replacement for aging VAIC slots without requiring firmware reconfiguration or rack redesign. Konmask.com stocks verified units sourced from decommissioned and surplus industrial assets, each subject to functional inspection prior to dispatch.

Technical FAQ
Q: Is IS200VAICH1DAB compatible with Mark VIe?
A: The IS200VAICH1DAB is designed for the Mark VI platform. Mark VIe uses a different I/O architecture (IONET vs. Ethernet-based). Cross-compatibility requires engineering review — contact us before ordering for Mark VIe applications.
Q: Can this card be used in a simplex (non-TMR) Mark VI configuration?
A: Yes. The VAIC card functions in both simplex and TMR configurations; rack slot assignment and ToolboxST I/O configuration determine the operating mode.
Q: What is the lead time for this part?
A: In-stock units ship within 1–3 business days. Express DHL delivery to most regions within 3–7 business days.
Q: Do you provide a test report or inspection certificate?
A: A basic inspection checklist is included with each shipment. Formal third-party testing certificates are available upon request at additional cost.
