National Instruments 781315-01 CompactRIO Chassis

Part Number 781315-01 is the identifying part number for the National Instruments NI-9159 CompactRIO Chassis. The 781315-01 is a 14-slot chassis that ships with an integrated MXI-Express that has a maximum cable length of 7 m. Likewise, it comes with a Virtex-5 LX110 FPGA that has 69120 flip-flops and 69120 6-input LUTs. Similarly, it has 64 DSP48 slices and a block RAM of size 4608 kbits. Furthermore, it has timebases of frequencies 40, 80, 120, 160, or 200 MHz and the accuracy is ±100 ppm (maximum).

The screw terminal wiring on the 781315-01 supports copper wires of thickness ranging from 24 AWG to 14 AWG. Likewise, the recommended wire strip length is 6 mm while the temperature rating is 85 °C. Similarly, the torque for the screw terminals must be between 0.20 Nm to 0.25 Nm. Additionally, connectors are secured using screw flanges, which have a torque of 0.3 to 0.4 Nm.

The 781315-01 supports input voltages from 9 VDC to 30 VDC and the maximum power input can be 55 W, 30 VDC. With no I/O modules, the chassis consumes a maximum power of 16.25 W while this can reach 32.7 W when 14 I/O modules are used. However, since these values are true for LabVIEW FPGA applications compiled at 80 MHz and can differ according to the user’s application. The 781315-01 is recommended for operation between temperatures of  0 °C to 55 °C at a relative humidity of 10% to 90%. Similarly, it is intended exclusively for indoor usage and ought to be used at elevations no higher than 2000 meters. On the other hand, it can be stored between  -40 °C to  85°C at a relative humidity of 5% to 95%.  

The maximum voltage allowed between the V to C terminal in the 781315-01 is 30 VDC under Measurement Category I. The module is designed to meet the requirements of many safety standards, including the EC 61010-1, EN 61010-1 UL 61010-1, CSA C22.2 No.61010-1, and more.
