National Instruments 784775-01 CompactRIO Controller

Part Number 784775-01 is the identifying part number for the National Instruments cRIO-9039 CompactRIO Controller. This device features an Intel Atom E3845 (1.91 GHz quad-core processor) with a shared on-die 2 MB L2 cache. It comes with 16 GB of nonvolatile memory (SSD) and 2 GB of DDR3L volatile memory supporting a theoretical data rate of 10.67 GB/s.

The 784775-01 is equipped with 2 network ports, supporting 10Base-T, 100Base-TX, and 1000Base-T Ethernet interfaces. These are compliant with IEEE 802.3 standards, and communication rates can be adjusted between 10 Mbit/s, 100 Mbit/s, and 1000 Mbit/s, with a maximum cabling distance of 100 meters per segment. Additionally, the controller provides USB 2.0 support through two host ports and one device port. Furthermore, the device features a mini DisplayPort that supports a resolution of up to 2560 x 1600 at 60 Hz.

The 784775-01 includes an RS-232 and an RS-485/422 port for serial communication. The RS-232 port supports baud rates of up to 115,200 bps, while the RS-485/422 port offers isolation and a maximum cable length of 30 meters. Additionally, the device is powered by a Xilinx Kintex-7 7K325T FPGA, which includes 203800 6-input LUTs, 840 DSP slices, and 16020 kbits of block RAM. It supports 16 DMA channels and 32 logical interrupts for efficient data handling. Screw terminal wire ranging from 20 AWG to 14 AWG is compatible with it. It is advised that the device be used in the following temperature range: -20 °C to 55 °C, 10% to 90% relative humidity. 

The 784775-01 measures 12.94 in. × 3.47 in. × 4.77 in. in physical dimensions and weighs 2250 g. It is compatible with 20 AWG to 14 AWG screw terminal wiring. The device is recommended for operation between temperatures of -20 °C to 55 °C at a relative humidity of 10% to 90% relative humidity. On the other hand, it can be stored at temperatures between -40 °C and 85 °C with a relative humidity range of 5% to 95%. Furthermore, it is designed for indoor use and up to a maximum altitude of 5000 m.
