Product Overview

DS3800HPRB is safety‑relay output board for GE Mark IV turbine‑control racks. It receives trip‑commands from main processor and drives hard‑wired safety‑relay contacts for turbine emergency‑trip, alarm and auxiliary‑interlock circuits, providing hardware‑level safety response independent of software logic. Critical obsolete safety‑hardware available as refurbished and new‑old‑stock spare parts for legacy power‑plant turbine‑protection‑system maintenance.

Application Notes

‑ Install inside Mark IV turbine‑control rack safety‑logic section. ‑ Respect relay contact load rating for field‑wiring design. ‑ ESD anti‑static handling mandatory for PCB replacement. ‑ Typical deployment: gas‑turbine power‑station emergency‑trip‑logic spare‑part stocking.
