GE IS200SAIIH1A Isolated Analog

الوصف

The GE IS200SAIIH1A is an Isolated Analog Input Card for the GE Mark VI (MKVI) turbine control system. This module’s main purpose is to read continuous (analog) signals from various sensors in the field while providing a crucial layer of electrical isolation to protect the sensitive control electronics.

Function and Purpose ⚙️

The primary function of the IS200SAIIH1A is to convert real-world analog signals—such as voltage or current from pressure, temperature, and flow transmitters—into a digital format that the Mark VI processor can understand. The “Isolated” part of its name is a key feature. It means that the card has a physical barrier that prevents ground loops and electrical noise from the field from affecting the control system’s internal circuitry. This isolation is critical for maintaining signal integrity and protecting the system from damage caused by voltage spikes. It ensures that the data used for control decisions is clean and accurate.

Key Features and Specifications

• Isolated Inputs: Provides electrical isolation for each input channel, protecting the system from external electrical noise and ground loops.
• High Resolution: The card provides high-resolution conversion of analog signals, ensuring a high degree of accuracy.
• Compatibility: It is designed to work seamlessly with other GE Mark VI control modules, including the main processor and I/O packs.
• Robust Design: Engineered to withstand the harsh conditions of industrial environments, including wide temperature ranges and high levels of vibration.
