PRODUCT INFORMATION
Product Overview
The General Electric IS220PPROS1B is an I/O Module designed for Mark VI / Mark VIe control systems. This module functions as a backup turbine protection I/O pack. The unit delivers an independent backup overspeed protection system alongside associated terminal boards. It also provides a backup synchronization check for generator connections to a utility bus.
A standard system uses three PPRO packs alongside designated terminal boards for turbine protection. The module monitors primary speed feedback and overall primary control operation to verify normal conditions. It also monitors the functional status of emergency trip boards through integrated feedback signals. The pack features two Ethernet communication ports within a modular rough vented chassis.
