GE DS215TCQAG1BZZ01A – Analog Input/Output Board | Mark V Turbine Control Platform
Engineering Background
The DS215TCQAG1BZZ01A is a precision analog signal conditioning board engineered by General Electric as a core I/O component within the Mark V Speedtronic™ turbine control system. Designed for continuous-duty industrial environments, this board manages the acquisition and output of analog process signals — including temperature, pressure, flow, and position feedback — that are critical to safe turbine operation and regulatory compliance.
Product Positioning
Targeted at maintenance engineers and procurement specialists managing GE Mark V-equipped gas turbines, steam turbines, and combined-cycle power plants, the DS215TCQAG1BZZ01A provides a direct OEM-equivalent replacement path. Konmask.com stocks verified surplus units sourced from decommissioned plant inventories and authorized distributors, enabling rapid field replacement without extended lead times from the OEM.

Technical FAQ
Q: Is the DS215TCQAG1BZZ01A compatible with Mark VI or Mark VIe systems?
A: No. This board is designed exclusively for the Mark V platform. Mark VI and Mark VIe use a different I/O architecture (VPRO/VTUR boards). Contact us if you need Mark VI equivalents.
Q: Can this board be repaired if it fails incoming inspection?
A: Yes. We can refer you to qualified GE Mark V repair facilities. Alternatively, we offer exchange programs — contact us for details.
Q: What is the typical lead time for surplus stock?
A: In-stock units ship within 1–2 business days of order confirmation. If out of stock, typical sourcing lead time is 2–4 weeks.
Q: Do you provide a Certificate of Conformance (CoC)?
A: Yes. A CoC documenting part number, serial number (if available), inspection results, and source is provided with every shipment upon request.
Q: What payment methods are accepted for international orders?
A: We accept T/T (wire transfer), PayPal, and major credit cards. For large orders, LC (Letter of Credit) arrangements can be discussed.
