The Abaco Systems / VMIC VMIVME-4116-060 is an 8-channel, 16-bit digital-to-analog converter board engineered for VMEbus-based industrial control and real-time data acquisition systems. Each channel delivers independently buffered voltage outputs with double-buffered data latches, enabling simultaneous updating across all eight channels. The board combines high-resolution conversion, tight accuracy specs, and integrated analog output isolation switches for comprehensive board-level diagnostics.
