  • Page 8 – Simultaneous AI– NI 9683 NI 9683 Circuitry The NI 9683 analog channels share a common ground that is isolated from other parts of the board. The NI 9683 protects each channel from overvoltages. Refer to the Specifications section for more information about overvoltage protection. The incoming analog signal on each channel is buffered and conditioned by the differential amplifier and then sampled by a 12-bit ADC.
  • Page 9 Then have a single connection from the plane to the CS COM pin of the NI 9683. The NI 9683 simultaneous analog inputs have ±10 V and ±5 V input ranges that can accommodate termination resistor values in a certain range, based on the sensor peak current.
  • Page 10 Use signal sources with an output impedance of less than 2 kΩ to ensure specified performance. Large source impedances add to the input resistor inside the NI 9683, which results in increased settling time and decreases the accuracy of the measurement. Increased input impedance also results in a decrease of the -3 dB bandwidth.

  • Page 11: Sinking Digital Output

    Sinking DO NI 9683 The NI 9683 has current sinking digital outputs, meaning that the output pin is driven to ground (GND) when the channel is ON. Make sure the devices you connect to the NI 9683 are compatible with the output specifications.
  • Page 12 The NI 9683 provides connections for four relay control digital output channels. Each channel has a relay control DO+ and a current return pin, relay control DO-. The NI 9683 has current sinking outputs, meaning the relay control DO+ is driven to relay control DO- when the channel is ON.
