The GE IS230TNEAH5AAX is a specialized ATEX-certified Emergency Trip DIN Rail Module for the GE Mark VIe control system. The “AX” in the part number indicates the module is certified for use in potentially explosive atmospheres. This assembly is designed for safety-critical emergency shutdown applications in hazardous locations and includes a terminal board and a PPRAS1BAX electronic I/O pack.
Key Features
- ATEX Certification: The “AX” signifies that the module has been certified for safe operation in hazardous environments where flammable gases, vapors, mists, or dust may be present. This is a critical safety requirement in industries like oil and gas.
- Emergency Trip Module: This module is a crucial part of a safety system. Its purpose is to process high-priority signals that trigger an immediate and safe shutdown, or “trip,” of a turbine or other critical equipment to prevent catastrophic failure.
- I/O Module Assembly: This is a complete, ready-to-install unit, consisting of both a terminal board and the specialized electronic I/O pack that processes the emergency trip signals.
- DIN Rail Mounting: The assembly is designed for standardized installation on a DIN rail, which simplifies wiring, saves space, and makes installation and maintenance more efficient.
- Mark VIe Integration: As part of the IS230 series, this assembly is a key component of the Mark VIe control platform, a system widely used for controlling gas and steam turbines.
Applications
The IS230TNEAH5AAX is used in critical industrial settings where a reliable emergency shutdown system is non-negotiable, especially in hazardous environments.
- Oil and Gas: In refineries and offshore platforms, it monitors critical parameters for emergency shutdown systems in areas with flammable materials.
- Power Generation: It is a core component in the emergency shutdown logic of gas turbines and other power generation equipment located in hazardous areas.
- Safety Instrumented Systems (SIS): The module’s design and ATEX certification make it suitable for use in safety-instrumented systems, where the goal is to bring a process to a safe state when dangerous conditions are met.
