The GE IS230TNEAH3A is a specialized Emergency Trip I/O module for the GE Mark VIe control system. It is a DIN rail-mounted assembly that includes a PPROS1B I/O pack, specifically designed for a high-speed, safety-critical emergency shutdown application, often referred to as “AEP” in GE’s product naming.
Key Features
- Emergency Trip Function: This module is a crucial component of a turbine’s safety system. It’s designed to process and act on signals that trigger a rapid and controlled shutdown, or “trip,” of the turbine to prevent damage or catastrophic failure.
- AEP (Advanced Emergency Protection): The “AEP” designation indicates that the module is part of a system with enhanced capabilities for emergency protection, often featuring redundant or high-speed processing to ensure a fail-safe shutdown.
- I/O Module Assembly: This is a ready-to-install unit, consisting of both the terminal board (where field wiring is connected) and the electronic I/O pack (PPROS1B) that processes the signals.
- Mark VIe Integration: As part of the IS230 series, this assembly is designed to seamlessly integrate with the Mark VIe control platform, a system widely used for controlling turbines in power generation plants.
Applications
The IS230TNEAH3A is used in critical industrial settings where a reliable emergency shutdown system is non-negotiable.
- Power Generation: It is a core component in the emergency shutdown logic of gas and steam turbines. It monitors critical parameters like overspeed, excessive vibration, or high temperature.
- Safety Instrumented Systems (SIS): The module’s design and function make it suitable for use in safety-instrumented systems, where the goal is to bring the process to a safe state when predefined dangerous conditions are met.
- Oil and Gas: In refineries and offshore platforms, it’s used to provide trip logic for compressors, pumps, and other critical equipment, ensuring that in the event of an emergency, the system can be safely shut down.
