National Instruments PCIe-7841 Multifunction Reconfigurable I/O Device
The PCIe-7841 is a Multifunction Reconfigurable I/O Device manufactured by NI. The part number of the NI PCIe-7841 is 781100-01. This device supports individual channel triggering and sampling at different rates. This model can be used to control signals. The PCIe-7841 has an onboard FPGA. The FPGA type is Virtex-5 LX30. The FPGA controls signal processing and provides flexible timing and synchronization for the system. Independent timing and triggering are also supported by the PCIe-7841. A dedicated ADC is incorporated for this purpose.
The NI PCIe-7841 Multifunction Reconfigurable I/O Device has eight analog input terminals, which can be used in three different modes: DIFF, RSE, and NRSE. The desired mode is selected through software. These terminals support an input signal in the range of +10 V. The PCIe 7841 can sample data at a maximum rate of 200 kS/s. The input terminals have the impedance of 10 GΩ.
The PCIe-7841 also features eight single-ended analog output terminals. These terminals have a maximum update rate of 1 MS/s. The impedance of the output channels of this device is 0.5 Ω. The analog terminals are DC-coupled and have a resolution of 16 bits. The PCIe-7841 offers overvoltage protection for the analog terminals; they can sustain up to +42V. The output terminal’s protection is the short circuit to ground.
The NI PCIe 7841 Multifunction Reconfigurable I/O Device comes with 96 digital I/O terminals. These digital terminals are TTL compatible. The digital terminals of the device support two logic levels: 3.3 V and 5V. The output current of the digital terminals is 4.0 mA. The digital terminals can sustain an overvoltage of +20 V without getting damaged.
