GE IS220PPROS1B Emergency Turbine Protection I/O Pack
GE IS220PPROS1B Emergency Turbine Protection I/O Pack
DESCRIPTION
The GE IS220PPROS1B Emergency Turbine Protection I/O Pack is an emergency turbine protection I/O pack manufactured and designed by General Electric (GE) as part of the Mark VIe family used in GE's distributed control systems.
Main features and functions
Emergency Protection: The IS220PPROS1B provides a standby overspeed protection system with a standby check function for synchronisation of the generator with the mains bus. It acts as a stand-alone monitor for the main control unit, ensuring a rapid response in case of emergency.
Triple Modular Redundancy (TMR): This I/O package supports a triple modular redundancy design, which improves system reliability and stability. The three PPRO I/O packs are mounted on separate simplex protection (SPRO) terminal blocks, forming a typical protection system.
Multiple connectors: The IS220PPROS1B is compatible with six discrete output terminal blocks, including SRLY and TRLY connections, as well as one DC connector and two RJ45 connectors, providing a wealth of connection options.
Ethernet communication: This I/O package connects to the control module via Ethernet for IONet communication, enabling high-speed, reliable data transmission.
Speed Signal Processing: The IS220PPROS1B is capable of processing three different types of speed signals, including hardware-implemented overspeed, acceleration, deceleration, and basic overspeed, ensuring accurate monitoring of turbine speed.
