The V280 is a single-wide, 6U VME module that includes 48 isolated logic inputs. It is available in versions for nominal 5 volt or 24 volt input levels. The V280 has independently programmable rising and falling edge response times to support contact debounce, glitch catching, and DC or AC inputs.
The V280 is protected against reverse polarity input and overvoltages, and includes fast, transparent built-in self-test (BIST).
