Features:
- Processes six pulse inputs across a wide frequency range for accurate rotational speed detection.
- Dual 100 Mbps IONet interfaces ensure stable and redundant data exchange with control systems.
- Three magnetic latching relays provide high-capacity switching for emergency shutdown operations.
General Electric IS220PPRAH1A is widely used in turbine protection systems where real-time monitoring and rapid response are required. It supports critical applications involving steam, gas, and hydro turbines by processing speed inputs and executing protection logic. The module integrates directly into turbine control architectures and provides stable performance under industrial conditions. Its electrical design supports consistent operation across a defined voltage range, ensuring reliability in demanding environments.
In operation, IS220PPRAH1A continuously processes six pulse signals to monitor turbine speed across a broad frequency range. This data is transmitted through dual 100 Mbps IONet interfaces, allowing seamless integration with control and protection systems. The module's trip logic relies on magnetic latching relays that deliver fast and stable switching performance. These features make IS220PPRAH1A suitable for applications requiring precise overspeed detection and immediate shutdown capability.
IS220PPRAH1A also supports flexible system configuration through compatibility with IS200TREAH1A terminal boards and IS200WREAH1A daughter boards. These combinations allow deployment in hazardous locations while maintaining safety performance. The module's robust design and environmental tolerance from -30°C to +65°C enhance its usability across various industrial sectors. As a result, IS220PPRAH1A provides a dependable solution for turbine protection and emergency control scenarios.
The IS220PPRAH1A General Electric Turbine Protection I/O Pack may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
