Kontron / Thales / Matrix MD-DAADIO8NFP Combination Board

The Kontron/Thales/Matrix MD-DAADIO8NFP is a 6U VMEbus combination board integrating analog and digital I/O on a single Eurocard for data acquisition and control applications. It consolidates 12-bit ADC and DAC converters with 48 TTL programmable I/O lines, eliminating the need for multiple boards while maintaining high performance and cost efficiency. Modular section population allows tailoring to specific mission requirements.
