High-speed eight-slot chassis for deterministic I/O

National Instruments Corporation (UK) Ltdvisit website


High-speed eight-slot chassis for deterministic I/ONational Instruments is launching a high-performance eight-slot chassis that delivers deterministic expansion I/O for the NI LabVIEW graphical development platform. The new chassis provides high-speed, jitter-free communication for applications such as distributed control, machine building and hardware-in-the-loop testing.

The NI 9144 eight-slot expansion chassis is compatible with more than 30 analogue and digital NI C Series modules for high-accuracy measurement quality and direct connectivity to a wide variety of sensors. The expansion chassis works with NI real-time controllers that have two Ethernet ports, including NI CompactRIO and PXI. The NI 9144 also features two Ethernet ports, making it possible for engineers to daisy-chain multiple NI 9144 chassis from a single controller to expand their time-critical applications while maintaining hard determinism with minimal processor resources. Using a system of synchronised clocks, the NI 9144 communicates deterministically across a standard CAT5 Ethernet cable and can be distributed up to 100m between chassis. With a temperature range of -40 to +70degC and 50g shock ratings, the rugged chassis is designed for industrial applications.

Easy to configure

Because the LabVIEW Real-Time Module 8.6 automatically recognises all connected slaves and modules, the NI 9144 works with minimal configuration. LabVIEW offers easy access to the physical channels, using the click-and-drag I/O variable, live test panels and I/O forcing for troubleshooting.

Integrating with NI technology such as FPGAs programmable with LabVIEW as well as industrial communications hardware and modular instruments, the new deterministic Ethernet chassis is suitable for applications such as machine building, large distributed systems, physics experiments and hardware-in-the-loop testing.
