National Instruments 786456-01 Multifunction Reconfigurable I/O Device.
The National Instruments 786456-01 (or PCle-7846) is a top-notch Multifunction Reconfigurable Digital I/O Device. It features a Kintex-7 160T FPGA for onboard processing and direct control over I/O signals. This device is designed for high-performance applications that require precise timing and control.
The 786456-01 includes 8 x analog input channels with software-selectable modes such as DIFF, NRSE, and RSE. It uses a Successive Approximation Register (SAR) type ADC with a resolution of 16 bits. The maximum sampling rate per channel is 500 kS/s that makes it suitable for high-speed data acquisition. The input impedance for this model varies depending on the power state, and it offers overvoltage protection up to ±42 V when powered on. This DAQ multifunction RIO device provides 8 x single-ended voltage output channels with a 16-bit resolution. The maximum update rate is 1 MS/s, facilitated by an Enhanced R-2R type DAC. The output range for this 786456-01 model is ±10 V with a current drive capability of ±2.5 mA. The outputs are protected against short circuits to ground and overvoltage conditions.
The digital I/O capabilities include 48 channels spread across two connectors. “Connector 0” supports a maximum frequency of 10 MHz, while “Connector 1” supports up to 80 MHz. The device is compatible with LVTTL and LVCMOS logic families, with a default setting of 3.3 V. The digital I/O channels are programmable for direction control and voltage selection at compilation. The reconfigurable Kintex-7 160T FPGA is installed in this 786456-01 model. It includes 202,800 flip-flops, 101,400 LUTs, and 11,700 kbits of Block RAM. It supports multiple timebases ranging from 40 MHz to 200 MHz. Data transfer is managed through DMA, interrupts, and programmed I/O.
This device interfaces with the host system via an x4 PCI Express slot and is compatible with x4, x8, and x16 PCI Express slots. It supports 16 DMA channels for high-speed data transfers. The power requirements depend on the digital output loads and the configuration of the LabVIEW FPGA VI used. The model weighs around 141.4 g and has dimensions of 16.8 cm x 11.1 cm. It features two 68-pin VHDCI connectors for I/O connections. The safety voltage limits for channel-to-earth and channel-to-channel are ±12 V and ±24 V. This unit can be used ideally under the temperature range of 0 to +55 degree Celsius. The humidity and altitude ranges for this 786456-01 model are 10% to 90% RH and 2000 MSL.
