Product Overview

IS220PPROH1A is emergency turbine‑protection I/O pack for GE Mark VIe control platform. It acquires turbine speed, emergency stop and critical interlock discrete signals, executes fast emergency‑trip logic for gas‑turbine and steam‑turbine units. TMR‑capable hardware meets power‑generation safety requirements, widely deployed in combined‑cycle and thermal power‑plant turbine‑control cabinets. Surplus and refurbished tested spare I/O pack for power‑plant control‑system overhaul and spare‑part stocking projects.

Application Notes

‑ Strict ESD anti‑static handling required during replacement. ‑ Verify field‑input voltage levels before power‑on. ‑ Perform protection‑logic function test after module swap‑out. ‑ Typical deployment: Mark VIe turbine‑emergency‑protection‑I/O‑pack spare‑part stocking.
