Product Overview

The IS220YPROS1AJ is a GE Mark VIeS backup turbine protection I/O module. The YPRO platform processes turbine-speed signals for an independent backup trip path rather than relying on the primary controller to make the protection decision. Its functions include overspeed detection, monitoring of primary-control operation and feedback from the associated trip board. Within a Mark VIeS protection system, YPRO works with the appropriate protection terminal board to carry speed and trip-related signals. This makes the module part of the backup protection layer for gas- and steam-turbine applications, including generator and mechanical-drive units.

Industries Served
-Power Generation: Provides a backup protection path in Mark VIeS-controlled gas- and steam-turbine generator systems.
-Oil and Gas: Relevant to turbine-driven compressors and other rotating equipment that uses a separate turbine trip architecture.
-Industrial Energy: Supports facilities operating turbine-based on-site generation or mechanical-drive equipment within a Mark VIeS control system.

Frequently Asked Questions

1. What is the main role of IS220YPROS1AJ?
It is listed as a backup turbine protection I/O module in the GE Mark VIeS family. The documented YPRO platform processes speed signals and contributes to the independent backup trip path.
2. Does YPRO depend on the primary controller to decide an overspeed trip?
No. GE describes YPRO’s local speed processing and trip functions as independent of primary-controller operation.
3. What else does YPRO monitor besides overspeed?
The documented platform can monitor acceleration, deceleration, primary-control operation and feedback from the selected trip board.
4. Are the input and output ratings the same with every terminal board?
No. GE specifies some ratings by terminal-board combination—for example, PT inputs with SPRO/TPRO boards and contact outputs with TREA boards.
