National Instruments NI-9147 Ethernet CompactRIO Chassis

The NI-9147 (Part numbers: 783496-01 and 783496-02) is a rugged Ethernet CompactRIO Expansion Chassis for NI C Series modules. This model has a Zynq-7000 (XC7Z020) FPGA, 512 MB nonvolatile memory, 256 MB DRAM, and a 10Base-T, 100Base-T, 1000Base-T Ethernet network interface, with IEEE 802.3 compatibility. The Chassis speeds up the expansion of the user’s real-time system by using the onboard FPGA for inline processing and high-speed I/O and control. The NI-9147 CompactRIO Chassis can also be easily incorporated with other expansion chassis systems, PXI systems, and computers that run Windows OS.

The difference between the two part numbers of the cRIO Chassis is that part number 783496-02 is conformal coated, while part number 783496-01 is not. A conformal coating is a thin protective layer applied to the circuit board to shield its parts from external elements such as dust, moisture, chemicals, and temperature changes.

The NI-9147 consists of a number of hardware components that enables deterministic distributed I/O. This slave Chassis features an RJ-45 Ethernet port and a USB Device port, utilizing a Zynq-7000 FPGA that functions as the C series module’s interface. The voltage input range of the chassis spans from 9 V DC to 30 V DC, with maximum reverse voltage protection of 30 V DC. The max power input when the chassis has 4 C Series Modules is 11 W, while an empty chassis has a max power input of 7 W.

The NI-9147 Ethernet CompactRIO Chassis has an internal Real-Time clock accuracy of 5 ppm and data rate up to 480 Mbps. This Chassis accepts a power range from 9 VDC to 30 VDC and has its maximum Reverse-voltage protection at 30 VDC. With four C Series modules, the power input is at 11 W, and at 7 W without C Series modules.

The environmental specifications of the device include an operating temperature range of -40 °C to 70 °C random as well as operational sinusoidal vibrations at 5 grms, 10 Hz to 500 Hz. When not being used, the storage temperature range is -40 °C to 85 °C. The physical dimensions of the NI-9147 are 7.01 in. × 3.44 in. × 2.50 in., and it weighs in at 23.98 oz.
