The GE IS215VCMIH2B is a VCMI TMR Card Kit for the Mark VI control system. The key feature of this card is its support for TMR (Triple Modular Redundancy), which is a critical design for systems that require the highest level of reliability and safety. The VCMI (VME Controller Module Interface) card serves as the communication bridge between the Mark VI controller and the I/O system.
Key Features and Applications
This module is a vital component for a fault-tolerant system, ensuring continuous operation even in the event of hardware failure.
- TMR (Triple Modular Redundancy): This is the most crucial feature. In a TMR system, three identical VCMI cards operate in parallel. They process the same inputs and a voting system is used to determine the correct output. If one card fails, the other two continue to function, ensuring that the system does not fail. This design provides maximum availability and safety, as it can tolerate two failures before losing its redundant capabilities.
- VCMI (VME Controller Module Interface): The VCMI card acts as a communication bridge, allowing the Mark VI controller to communicate with various I/O and field devices over the VME bus. This seamless communication is essential for real-time data acquisition and control.
- Component of a Kit: The “Kit” designation indicates that the part number likely includes not just the card itself, but also associated hardware or documentation needed for installation, simplifying the setup process for TMR systems.
- Data Processing: The card processes the I/O data, converting signals from field devices into a format the main controller can understand and vice versa. This ensures accurate and efficient control of machinery.
Common Applications
The GE IS215VCMIH2B is commonly used in mission-critical applications where uninterrupted control is non-negotiable, including:
- Power Generation: Used in turbine control systems to prevent overspeed or other catastrophic failures.
- Oil and Gas: Deployed in safety systems for pipelines, offshore platforms, and refineries.
- Industrial Processes: In any application where a control system failure could lead to significant financial loss, environmental damage, or a risk to human life.
