The NI 9144 is an 8-slot rugged chassis for NI C Series modules you can use to add deterministic, distributed I/O to programmable automation controller (PAC) systems. With standard CAT 5 Ethernet cabling, it communicates deterministically with any NI CompactRIO or real-time PXI system that has two Ethernet ports. You can daisy chain multiple NI 9144 slave chassis from the controller to expand time-critical applications to high-channel counts while maintaining hard determinism with minimal processor resources.

The chassis works with more than 30 C Series modules for analog and digital I/O, delivering direct connectivity to a wide variety of sensors and reusability with other NI hardware platforms. Additionally, the out-of-box experience has minimized configuration for the NI 9144 chassis by automatically recognizing all connected slaves and their modules with the NI LabVIEW Real-Time Module. With LabVIEW, you have easy access to the physical channels using the click-and-drag I/O variable, live test panels, and I/O forcing for troubleshooting.
