Product Overview

IS200TRPGH2B is a specialised termination‑board assembly for Mark VIe turbine overspeed‑protection and trip‑gate logic. It handles field‑wiring connections for magnetic‑pickup speed sensors and routes speed‑sensor signals to turbine‑protection processing boards, also distributing gate‑drive trip‑control signals within the safety‑logic rack. This board is critical hardware for gas‑turbine and steam‑turbine overspeed‑protection‑subsystem physical‑signal‑interface. Obsolete turbine‑protection spare PCB assembly available as refurbished and surplus tested units for legacy power‑plant‑safety‑rack overhaul projects.

Application Notes

‑ Route magnetic‑pickup shielded cables separately away from high‑voltage power cables to reduce EMI interference. ‑ Verify backplane connector full seating after board replacement. ‑ Perform overspeed‑protection function test after board swap‑out per plant safety‑maintenance procedure. ‑ Typical deployment: power‑plant Mark VIe turbine‑protection‑gate terminal‑board spare‑part stocking.
