Acromag AVME9668 VMEbus 6U IP Carrier Card

The Acromag AVME9668 is a 6U VMEbus non-intelligent slave carrier card that interfaces up to four IndustryPack (IP) modules with VMEbus systems. It enables modular I/O customization by accepting single or double-sized IP modules (32-bit modules not supported) and provides full data access to each module's I/O, ID, and memory spaces through VMEbus software control. All field I/O connections route through front-panel SCSI-2 connectors with screw-down or spring latch mechanisms and shielded cable paths for noise immunity.
