Page 4: Analog Input
Analog Input The PCIe-7846 provides connections for eight AI channels. Each channel has an AI+ pin, AI- pin, and AIGND pin to which you can connect both single-ended or differential voltage signals. Use the AISENSE pin to connect non-referenced single-ended signals. - Page 5 AI+ and the negative voltage signal to AI-. To connect grounded differential signals to the PCIe-7846, you must also connect the signal reference to AI GND. Figure 4. Connecting Grounded Differential Signals to the PCIe-7846...

Page 7: Field Wiring Considerations
When the system powers on, the DIO channels are set as input low with pull-down resistors. To set another power-on state, you can configure the NI PCIe-7846 to load a VI when the system powers on. The VI can then set the DIO lines to any power-on state. -
Page 8: Power Source
Separate NI PCIe-7846 signal lines from high-current or high-voltage lines. These lines can induce currents in or voltages on the NI PCIe-7846 signal lines if they run in parallel paths at a close distance. To reduce the magnetic coupling between lines, separate them by a reasonable distance if they run in parallel or run the lines at right angles to each other. -
