GE IS220PPROS1B Emergency Turbine Protection I/O Pack
Manufacturer: General Electric (GE Vernova)
Model: IS220PPROS1B
Type: Emergency Protection I/O Pack (PPRO)
System: Mark VIe Speedtronic Turbine Control
Safety Level: SIL3 (TMR Triple Modular Redundancy)
1. Overview
The GE IS220PPROS1B (PPRO) is a high-reliability emergency protection I/O pack for Mark VIe turbine control systems. It provides safety-critical input/output interfaces for gas/steam turbine emergency shutdown (ESD), integrating high-speed discrete inputs and relay outputs for trip logic. Designed for TMR SIL3 applications, it ensures fault-tolerant protection in power generation and oil & gas environments.
