GE IS220PTURH1A Turbine‑Specific Primary Trip I/O Pack

 

Product Brand & Model Title

Official Product Name: Turbine‑Specific Primary Trip I/O Pack Brand: General Electric (GE Energy) Model No: IS220PTURH1A Alternative Part: IS220PTURH1AD Product Grade: Safety‑critical turbine protection I/O pack for Mark VIe Speedtronic control system, TMR‑capable industrial grade moduleMoore Auto…

 

General Product Overview

The IS220PTURH1A is a dedicated primary turbine trip I/O pack for GE Mark VIe Speedtronic distributed turbine control system. It acquires high‑priority safety signals including turbine speed, emergency stop and trip‑chain status from field sensors, executes primary overspeed and emergency trip protection logic, and communicates protection data to Mark VIe controller via IONet dual‑Ethernet network. It supports simplex and TMR triple‑modular‑redundant deployment for different safety‑level requirements. Equipped with conformal coating, it adapts to high‑vibration, wide‑temperature turbine‑skid environment. This module mates with TTURH1C terminal board via 62‑pin DC connector, providing electrical isolation between field devices and control hardware for gas & steam turbine safety protection loopsMoore Auto….
