The NI ‑ 9375 is a digital I / O interface that uses industrial logic levels and signals so it can be connected directly to a wide variety of industrial switch modules, converters, and other devices. All digital inputs are compatible with 24 V logic levels and all output lines with signals from 6 to 30 V, depending on the external power supply. The NI-9375 has isolation between the input and output banks and resistance isolation from channel to ground.
