– Key Features
• PXI trigger lines routed to each slot for synchronized peripheral module operation
• Dedicated Star Trigger slot for ST-compatible modules
• Three controller expansion slots enabling left-bound expansion without consuming peripheral slots
• Removable, modular power supply shuttle
• Rear panel 9-pin D-SUB connector for remote power status and inhibit functions
– Typical Applications
• Automated test equipment (ATE) systems
• Multi-channel data acquisition platforms
• Industrial control and monitoring systems
• Mixed-signal test automation
– Compatibility & Integration
Fully interoperable with standard CompactPCI modules. System controller expansion accommodates multi-slot controller requirements while preserving peripheral slot availability. Selectable AC or DC power input enables operation in diverse deployment environments.
