Description
GE IS220PPROH1A
- Technical Specifications:
- Series: GE Mark VIe
- Function: Backup/auxiliary turbine protection I/O
- Compatibility: Used with TREAH_A terminal boards for emergency trip applications
- Inputs/Outputs: Designed for discrete signals critical to protection
- Wiring limits: Field wiring limited to 1000 feet due to voltage detection requirements
- Functional Features:
- Direct interface to field protection devices (e.g., overspeed, vibration, pressure switches)
- Supports high-integrity emergency trip functions
- Suitable for use in hazardous and non-hazardous locations (verify with terminal board and approvals)
- Application Scenarios:
- Aero-derivative turbine emergency trip systems
- Auxiliary protection in gas and steam turbines
- Applications requiring separate backup protection channels
- Performance Parameters:
- Designed for fast and reliable response to trip conditions
- Complies with safety-related requirements for turbine protection
- Material and Structural Characteristics:
- Rugged housing and connectors for industrial environments
- Conformal coating available for harsh conditions
- Working Principle:
- The module monitors critical protection signals from field devices and, upon detecting a trip condition, initiates shutdown actions via dedicated outputs. It communicates status and events to the Mark VIe controllers.
- Installation Requirements:
- Install with compatible TREAH_A terminal board per GE drawings
- Adhere to wiring length limits (1000 feet) for field connections
- Use appropriate shielding and terminations
- Usage Notes:
- Confirm wiring length and voltage detection requirements
- Use in conjunction with main protection systems for redundancy
- Regularly test trip functions to ensure reliability
