NI-9474

30 V, 8-Channel (Sourcing Output), 1 µs C Series Digital Module — The  NI9474 works with industrial logic levels and signals to connect directly to a wide range of industrial switches, transducers, and devices. Each channel is compatible with signals from 5 V to 30 V, features transient overvoltage protection between the output channels and earth ground, and includes an LED that indicates channel status. The NI9474 is a correlated digital module capable of performing correlated operations, triggering, and synchronization when installed in a CompactDAQ chassis.
