Versalogic VL-1225 STD Bus Analog I/O Card

The Versalogic VL-1225 STD Bus Analog I/O Card delivers integrated analog signal acquisition and control for embedded systems and industrial applications. This single-board solution combines 16 single-ended or 8 differential analog inputs with dual analog outputs, all accessible through a standard STD Bus interface. The card operates from a single +5 V supply with onboard DC-to-DC conversion, eliminating external power conditioning requirements.
