Kontron / Thales / Matrix MD-DAADIO8NAP Combination Board

The Kontron/Thales/Matrix MD-DAADIO8NAP is a double-height VMEbus combination board integrating analog-to-digital converters, digital-to-analog converters, and programmable input/output functions for data acquisition and distribution in embedded systems. Selective population of functional sections enables cost-effective configuration tailored to specific application requirements, reducing system complexity versus multi-board implementations.
