Overview
The General Electric IS220PPROH1A REV.E is a Turbine Protection I/O Pack from the Mark VIe Speedtronic series, manufactured by GE and now managed by GE Vernova. Designed for industrial automation, it provides critical turbine protection functions by processing inputs from speed, vibration, and other sensors, and generating outputs for emergency shutdowns in gas and steam turbine systems. It supports both simplex and Triple Modular Redundant (TMR) configurations and is used in power generation, oil and gas, and industrial manufacturing to ensure safe and reliable turbine operation.
