Using the SCB-100 with Multifunction I/O Devices

You can take measurements with the SCB-100 and multifunction I/O (NI 60xxE) devices in a number of ways. The SCB-100 has a temperature sensor for cold-junction compensation to accommodate thermocouples. Switches S4, S5, and S6 configure the temperature sensor for different analog input settings. The following table shows the different switch settings for multifunction I/O devices.

MIO with disabled temperature sensor mode (default configuration)—Move switches S1, S2, S3, S4, S5, and S6 to the positions shown on the left. In this mode:

  • The temperature sensor is not used.
  • AI 0 and AI 8 are available on screw terminals.
  • The signal accessory power LED (DS1) lights when the device is powered and connected to the SCB-100.

Refer to the following figure for a detailed diagram.

MIO with single-ended temperature sensor mode—Move switches S1, S2, S3, S4, S5, and S6 to the positions shown on the left. In this mode:

  • The temperature sensor can be read using AI 0 in referenced single-ended (RSE) mode.
  • AI 8 is available on a screw terminal.
  • The signal accessory power LED (DS1) lights when the device is powered and connected to the SCB-100.

Refer to the following figure for a detailed diagram.

MIO with differential temperature sensor mode—Move switches S1, S2, S3, S4, S5, and S6 to the positions shown on the left. In this mode:

  • The temperature sensor can be read using AI 0 and AI 8 in differential mode.
  • The signal accessory power LED (DS1) lights when the device is powered and connected to the SCB-100.

Refer to the following figure for a detailed diagram.
