Product Overview

DS3800HMPK is the core microprocessor board for GE Speedtronic Mark IV gas‑steam turbine control system. It runs critical turbine‑start‑up sequence, speed‑governing, load‑control and safety‑interlock calculations, exchanges real‑time data with other rack I/O and interface boards. This end‑of‑production CPU board is supplied as rebuilt / refurbished and new‑old‑stock spare parts for legacy power‑plant turbine‑unit overhaul projects.

Application Notes

‑ Insert into designated CPU slot inside Mark IV control rack. ‑ Verify firmware revision compatibility with existing system configuration. ‑ Observe full ESD protection during module replacement. ‑ Typical deployment: combined‑cycle power‑plant Mark IV turbine‑control spare‑part stocking.
