Product Overview

DS3800HMPJ1AID is processor‑extension auxiliary board for GE Speedtronic Mark IV platform. It works cooperatively with HMPK main CPU board to expand system memory and parallel bus throughput for complex turbine‑sequence and protection‑logic. It handles high‑speed event‑data buffering for unit trip‑post‑mortem analysis. Discontinued OEM board available as refurbished and new‑old‑stock spare parts for legacy turbine‑control‑rack maintenance.

Application Notes

‑ Install in adjacent slot paired with DS3800HMPK main processor board. ‑ Confirm hardware revision compatibility before commissioning. ‑ Strict ESD precautions required during board swap. ‑ Typical deployment: combined‑cycle power‑plant Mark IV turbine‑control spare‑part stocking.
