    The provided clock source must be stable and glitch-free. Ground connection Supply (+5 V ) 5 V power output connection for external devices No connection The NI PXIe-7867R is protected from overvoltage and overcurrent conditions. Refer to the device specifications, available at ni.com/manuals for more Note information.

  • Page 5: Analog Input

    Analog Input The NI PXIe-7867R provides connections for six 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 6: Connecting Differential Voltage Signals

    You can connect grounded or floating differential signal sources to the NI PXIe-7867R. Connect the positive voltage signal to the AI+ and the negative voltage signal to AI-. To connect grounded differential signals to the NI PXIe-7867R, you must also connect the signal reference to AI GND.
  • Page 7 Accessory Digital I/O The NI PXIe-7867R provides connections for 48 digital input/output (DIO) channels. Connector 0 contains 16 low-speed channels that can run up to 10 MHz signal frequencies and Connector 1 contains 32 high-speed DIO channels that can run up to 80 MHz signal frequencies.

  • Page 8: 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 PXIe-7867R to load a VI when the system powers on. The VI can then set the DIO lines to any power-on state. Visit ni.com/info...

  • Page 9: Worldwide Support And Services

    Never connect the +5 V power terminals to analog or digital ground or Caution any other voltage source on the NI PXIe-7867R or any other device. Doing so can damage the device and the computer. National Instruments is not liable for damage resulting from such a connection.
