Note The pinout label on the lid of the SCB-68A accessory is incompatible with the NI PXIe-7867R. Refer to the NI 78xxR Pinout Labels for the SCB-68A, available at ni.com/manuals for the compatible pinout labels. -
Page 6: Analog Input
VHDCI (2 m) 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 7 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.

AIGND Connection Accessory NI PXIe-7867R Analog Output The NI PXIe-7867R provides connections for eighteen analog output channels. Each channel has an AO pin and AOGND pin to which you can connect a load. Figure 6. Connecting a Load LOAD AOGND... - Page 9 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.

Page 10: Field Wiring Considerations
Separate NI PXIe-7867R signal lines from high-current or high-voltage lines. ■ These lines can induce currents in or voltages on the NI PXIe-7867R 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. -
Page 11: Power Source
Caution Never connect the +5 V power terminals to analog or digital ground or 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.
