Product Overview

DS3800HXPD is bus‑expander auxiliary board for GE Mark IV turbine‑control racks. It extends the internal high‑speed parallel backplane bus, allowing the system to accommodate larger quantities of I/O and auxiliary‑interface boards for complex multi‑unit turbine‑plant configurations. This discontinued expander‑hardware is available as refurbished and new‑old‑stock spare parts for legacy power‑plant‑control‑rack expansion‑maintenance.

Application Notes

‑ Install in designated bus‑expansion slot of Mark IV rack. ‑ Follow rack‑bus‑segment configuration rules per GE system‑manual. ‑ Mandatory ESD protection during board replacement. ‑ Typical deployment: large combined‑cycle‑power‑plant Mark IV turbine‑control‑rack spare‑part stocking.
