The GE IS230STCI2ASTCI2AG01 is a dual-redundant discrete input assembly for the GE Mark VIe control system. This module is designed for high-reliability applications where a loss of a digital input signal would be catastrophic, ensuring continuous operation even if one of the modules fails.
Key Features
- Discrete Input: The module’s primary function is to handle binary or on/off signals. It reads the state of devices like switches, relays, and push-buttons, converting these physical states into digital signals that the Mark VIe controller can use.
- Dual Redundancy: The part number indicates a dual assembly, meaning it contains two identical discrete input 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, which is essential for critical applications.
- 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 data acquisition needed for critical safety and control loops.
Applications
The IS230STCI2ASTCI2AG01 is used in industrial settings where a loss of a digital input could lead to a catastrophic event or significant downtime.
- Power Generation: It is used in power plants to monitor the status of critical devices on gas and steam turbines, such as valve limit switches, motor run/stop indicators, and emergency trip buttons. The redundancy ensures that even if a module fails, the control system still receives vital safety data.
- Oil and Gas: In refineries and offshore platforms, it helps monitor critical discrete signals where continuous operation is essential, such as the open/closed status of emergency shutdown valves or the state of fire and gas detectors.
- Critical Safety Systems: The module is a fundamental component in any safety system where a failure to monitor a digital signal could result in significant equipment damage or a safety risk.
