Product Overview

IS200TPROH1C is a termination‑board assembly dedicated to Mark VIe turbine‑protection‑processor racks. It provides field‑wiring termination for turbine‑protection interlock‑contact inputs, emergency‑trip‑system feedback‑signals and protection‑logic output‑control‑signals, routing field‑signals to turbine‑protection‑processor boards. It participates in gas‑turbine and steam‑turbine safety‑trip‑logic signal‑path within the Mark VIe control architecture. Obsolete safety‑system spare‑PCB assembly available as refurbished and surplus tested hardware for legacy power‑plant‑turbine‑protection‑rack overhaul‑projects.

Application Notes

‑ All protection‑trip‑circuit field‑wiring shall comply with plant safety‑instrumented‑system installation‑standards. ‑ Ensure full backplane‑connector seating after board replacement. ‑ Execute complete protection‑logic function‑verification test after board swap‑out. ‑ Typical deployment: power‑plant Mark VIe turbine‑protection‑processor terminal‑board spare‑part stocking.
