Description
The GE IS430SNUAH1A is a Universal I/O Module for the GE Mark VIe control platform. It combines the SUAAH1A terminal board with the PUAAH1A I/O pack to provide flexible signal acquisition and processing for industrial control applications.
The module supports multiple field signal types, allowing individual channels to be configured for thermocouples, RTDs, voltage, current, pulse, or digital signals. This makes it suitable for process control and turbine-control applications where different field instruments need to share a common I/O platform.

⚡ Functional Description
The IS430SNUAH1A digitizes field signals, executes local I/O processing, and communicates the resulting data with the Mark VIe controller. GE’s Mark VIe architecture uses a processor board together with a device-specific data acquisition board to process field signals and provide diagnostic information to the controller.
The 16 channels can be individually configured for different signal types. This provides a useful amount of flexibility when a control cabinet contains a mixture of temperature, voltage, current, pulse, and discrete signals.
🔌 Configuration & Commissioning
Basic configuration procedure:
• Install the IS430SNUAH1A in the designated Mark VIe location
• Verify the SUAAH1A terminal board connection
• Connect field wiring according to the project drawings
• Configure individual channels in ToolboxST
• Select the appropriate signal type
• Set input/output scaling and engineering units
• Verify controller communication
• Check I/O diagnostics
During commissioning, verify each channel independently before placing the equipment into normal automatic operation.
🛠️ Installation Notes
Before replacement, verify:
• Complete part number IS430SNUAH1A
