GE IS220PTURH1A – Mark VIe Primary Turbine Trip I/O Pack

Product Overview

IS220PTURH1A is a turbine‑specific primary trip I/O pack for the GE Mark VIe Speedtronic control system. It acquires critical speed, emergency stop and protection sensor signals, executes local trip logic, and exchanges safety data with the main turbine controller over dual redundant IONet Ethernet. This front‑line protection hardware forms the core safety interface between field transducers and the turbine shutdown system in power plants.
