Detailed data
GE IS220PPRAH1A Emergency Turbine Backup Protection I/O Module
The IS220PPRAH1A is an Emergency Turbine Protection (PPRA) I/O pack and associated TREA Terminal Board providing an independent backup overspeed protection system. The protection system consists of three Triple Modular Redundant PPRA I/O packs mounted on the TREA Terminal Board, including the WREA option board. The PPRA is a derivative of the standard Mark VIe PPRO Emergency Turbine Protection I/O pack. Most of the configuration, variables and behavior of the PPRA are the same as in the PPRO. The PPRA is specific to the TREA Terminal Board equipped with the WREA option board. The PPRA mounts directly on the TREA, and when using the TREA, the WREA option board needs to be mounted on the PPRA dedicated circuit board option header connector. The PPRA and WREA mounted on the TREA will only function properly when three PPRA I/O packs are used.
