Product Overview

IS220PPROS1B is a safety‑oriented protection‑I/O pack for GE Mark VIe and Mark VIeS turbine‑safety‑control‑systems. It processes rotational‑speed signals, emergency‑trip‑interlock discrete‑inputs and executes fast‑response turbine‑protection‑logic functions including overspeed‑detection and trip‑command generation. Dual‑port redundant IONet network supports fault‑tolerant safety‑system architecture for gas‑turbine and steam‑turbine power‑generation units. Safety‑relevant signal‑path diagnostics continuously monitor circuit‑continuity to detect open‑circuit or short‑circuit fault‑conditions. End‑of‑life safety‑system spare component available as refurbished and surplus tested hardware for legacy power‑plant‑protection‑rack maintenance‑projects.

Application Notes

‑ Install onto matching PPRO‑series terminal‑base assembly; strictly follow plant safety‑instrument‑system installation‑procedures. ‑ Perform full protection‑logic function‑verification test after module replacement. ‑ Configure safety‑logic parameters inside ToolboxST engineering software. ‑ Typical deployment: power‑plant Mark VIe turbine‑protection‑I/O‑pack spare‑part stocking.
