The GE IS230TAISH1C is a basic analog I/O assembly for the GE Mark VIe control system. This module, operating in a simplex configuration, is rated for use in Safety Instrumented Systems (SIL), making it suitable for applications where safety and reliability are critical.
Key Features
- Analog I/O: The module is designed to handle both analog inputs and outputs. It receives continuous signals from field devices like pressure and flow transmitters and sends continuous signals to devices like valves and actuators, enabling both monitoring and control of a process.
- Safety Integrity Level (SIL): The SIL rating is a crucial feature. It means the module has been designed and certified to meet specific safety standards, with a low probability of failing in a dangerous way. This makes it a core component for building a safety instrumented system.
- Simplex Configuration: The term “simplex” indicates a single, non-redundant unit. While not as fault-tolerant as a redundant system, its SIL rating makes it a reliable choice for safety applications where redundancy is not required or is handled at a higher system level.
- 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 gas and steam turbines.
Applications
The IS230TAISH1C is used in industrial settings where a combination of analog control/monitoring and a high level of safety is required.
- Power Generation: It is used in turbine control systems to monitor and control critical variables like fuel flow or pressure in a safety-rated manner, ensuring that the control system can safely trip the turbine if an unsafe condition is detected.
- Process Safety: It can be used in various industrial processes to provide a safety-rated interface for controlling valves or other actuators that are part of an emergency shutdown system.
- Oil and Gas: In refineries and offshore platforms, it helps manage critical process variables with a high degree of reliability to prevent hazardous conditions.
