1 DATASHEETNI 94728 DO, 6 V to 30 V, Sourcing, 100 s DSUB, screw-terminal, or spring-terminalconnectivity CompactDAQ counter compatibility 250 Vrms, CAT II, channel-to-earth isolation(screw and spring terminal); 60 VDC, CAT I,channel-to-earth isolation (DSUB)The NI 9472 is a digital output module for CompactDAQ and CompactRIO systems. Eachchannel is compatible with 6 V to 30 V signals and features 2,300 Vrms of transientovervoltage protection between the output channels and the backplane. Each channel also hasan LED that indicates the state of that channel. With the NI 9472, you can connect directly to avariety of industrial devices such as motors, actuators, and are three connector options for the NI 9472 a 10-position screw-terminal connector, a10-position spring-terminal connector, and a 25-position DSUB connector.
