Overview
The General Electric IS220YPROS1A is a Backup Turbine Protection I/O Pack from the Mark VIeS Speedtronic series, manufactured by GE and now managed by GE Vernova. Designed for industrial automation, it provides backup protection for gas and steam turbines by processing critical inputs like speed and flame detection, and generating outputs for emergency shutdowns. It supports Triple Modular Redundant (TMR) configurations for safety-critical applications and is used in power generation, oil and gas, and industrial manufacturing to ensure safe turbine operation.
