NI 9423 24 V, Sinking Digital Input, 8 Ch Module

Starting at $ 296 (view pricing options)
The NI 9423 is an 8-channel, 1 µs high-speed sinking digital input C Series module for any NI CompactDAQ or CompactRIO chassis. Each channel can input up to 30 V discrete voltage levels, is compatible with 24 V signals, and features transient overvoltage protection of 2,300 Vrms between the input channels and earth ground. Each channel also has an LED that indicates the state of that channel. The NI 9423 works with industrial logic levels and signals to directly connect to a wide array of industrial switches, transducers, and devices.

The NI 9423 module is a correlated digital module, so it can perform correlated operations, triggering, and synchronization when installed in an NI CompactDAQ chassis.
