System Architecture & Signal Flow
Within the Mark V cabinet, the DS200TCCBG3BDC resides on the analog I/O backplane and communicates with the TCCA / TCCB processor boards via the internal VME-style bus. Analog field signals enter through terminal board connectors (typically JR1/JR2 on the TREG or TCEA terminal boards), are conditioned and digitized on the DS200TCCBG3BDC, then passed to the triple-redundant voting logic in the Mark V ,
Sourcing & Quality Verification
- All DS200TCCBG3BDC units are individually inspected upon receipt
- Visual inspection: PCB traces, component seating, connector pin integrity

- Photographic documentation of part number label provided on request
- Counterfeit-avoidance protocol: sourced exclusively from decommissioned OEM installations or authorized surplus channels
Procurement Process
- Confirm compatibility: Verify your Mark V cabinet revision and TCCB/TCCA board revision against DS200TCCBG3BDC revision suffix (G3BDC)
- Request quote: Contact [email protected] with your PO requirements, delivery address, and required lead time
- Order confirmation: Receive proforma invoice with unit serial/inspection record
- Shipping: DHL / FedEx express international; EXW Xiamen or DAP destination available
- Incoming inspection: Konmask provides test report and label photos to support your incoming QC
Technical FAQ
Q: Is DS200TCCBG3BDC interchangeable with DS200TCCBG1A or DS200TCCBG2A?
A: Revision suffixes indicate hardware ECO changes. G3BDC is not always backward-compatible with earlier revisions. Confirm with your GE Mark V system documentation or contact our engineers before substituting.
Q: Can this board be used in Mark VI or Mark VIe systems?
A: No. DS200-series boards are exclusive to the Mark V platform. Mark VI uses DS200 form factor in some I/O packs but with different firmware and backplane protocols — cross-platform use is not supported.
Q: Do you provide a test report?
A: Yes. A functional test summary is available upon request prior to shipment.
Q: What is the lead time?
A: In-stock units ship within 1–3 business days. Out-of-stock sourcing typically requires 2–4 weeks.
Q: Can you supply multiple units for a fleet spare program?
A: Yes. Contact us for volume pricing and consignment stocking arrangements.
