The GE IS230STAO2ASTAO2AG21 is a dual-redundant analog output assembly for the GE Mark VIe control system. This module is designed for high-reliability applications where a loss of control signal would be catastrophic, ensuring continuous operation even if one of the output modules fails.
Key Features
- Analog Outputs: The module’s primary function is to generate and transmit analog signals, typically 4-20 mA or 0-10V, to control devices like actuators and control valves. This allows for precise and continuous control of a process variable.
- Dual Redundancy: The part number indicates a dual assembly, meaning it contains two identical analog output modules operating in parallel. This configuration ensures that if one module fails, the other can take over seamlessly without any interruption to the process. This redundancy is a core component of the Mark VIe’s high-reliability architecture.
- Mark VIe Integration: This assembly is a key part of the Mark VIe platform, ensuring seamless integration and compatibility with the main controller. It provides the high-speed and reliable control needed for critical analog loops.
Applications
The IS230STAO2ASTAO2AG21 is used in industrial settings where the loss of an analog output signal could lead to a catastrophic event or significant downtime.
- Power Generation: It is used in power plants to precisely control critical variables on gas and steam turbines, such as fuel flow rates, lubrication oil pressure, and valve positions. The redundancy ensures that even if a module fails, the turbine continues to operate safely.
- Oil and Gas: In refineries and offshore platforms, it helps manage critical process variables where continuous operation is essential, such as controlling the flow of a catalyst or regulating pressure.
- Critical Process Control: The module is a fundamental component in any process where a failure in control could result in significant equipment damage or safety risks.
