National Instruments NI-9144 CompactRIO Chassis

The NI-9144 CompactRIO Chassis by National Instruments can be incorporated with the LabVIEW FPGA Module, given its 2M gate Xilinx Spartan FPGA. (Part Numbers: 780438-01, 780438-02) This allows high-speed and customizable I/O timing, inline processing, and closed-loop control. This CompactRIO Chassis also features a scan mode that can be configured to quickly perform an extension of the user’s real-time system. This model has two part numbers: part number 780438-01 does not have conformal coating, while part number 780438-02 does have conformal coating. Multiple NI 9144 Expansion Chassis can be daisy-chained from the master controller to expand applications that are time-critical to high channel counts, while maximizing the utility of processor resources in maintaining hard determinism.

All I/O modules are automatically synchronized in each Chassis and are also synchronized with each other. By plugging in additional modules, the NI 9144 EtherCat Chassis becomes a versatile modular expansion system that can integrate multiple measurement types and channels when the user plugs in additional I/O modules. Individually, the modules contain inherent signal conditioning and isolation for industrial signal measurement types. Additionally, the device has 8 slots.

To operate the NI 9144, a variety of software is required. They must be installed in the following order: LabVIEW 2016 or later versions, LabVIEW 2016 Real-Time Module or later versions, NI CompactRIO Device Drivers August 2016 or later versions, NI-Industrial Communications for EtherCat 16.1 or later versions, LabVIEW 2016 FPGA Module or later versions. The NI 9144 can be connected to a NI master controller by using a category 5 Ethernet cable. Before the connection is carried out, the NI master controller must be connected to a network.

The NI 9144 has a recommended power supply of 48 W, 24 VDC and a maximum power consumption of 20 W and an input range from 9 V to 30 V. In a storage environment, ambient temperature is from 40 °C to 85 °C. The operating shock is at 30 g, 11 ms half sine; 50 g, 3 ms half sine. The device is equipped with an EtherCat bus connector. The device weighs 32.7 oz and has the dimensions: 11.28 x 3.47 x 2.32 in.

NI-9144 Obsolete Status has been declared by National Instruments, but the chassis will still be available for purchase and repairs by Apex Waves.
