INSTALLATION GUIDE
SCB-100
100-Pin Shielded Desktop Connector Block
This guide describes how to connect and use the NI SCB-100 with 100-pin data acquisition (DAQ)
devices. The SCB-100 is a shielded desktop accessory with 100 screw terminals, a cold-junction
compensation temperature sensor for use with thermocouples, and a strain-relief bar for securing signal
wires or cables. The SCB-100 connects to E Series MIO devices (NI 6025E, NI 6031E, NI 6033E,
and NI 6071E), DIO devices (PCI-DIO-96, NI 6508, NI 6509, NI 6511, NI 6512, NI 6513, NI 6514,
NI 6515, NI 6527, and NI 6528), TIO Series devices (NI 6624), or other products with a 100-pin
0.050 series shielded D-type I/O connector.
Note
To use the SCB-100 with a DIO or TIO Series device, you must change the default switch
setting. Refer to the
Figure 1 shows the SCB-100 connector block.

Summary of Contents for National Instruments SCB-100

  • Page 1: Table Of Contents

    The SCB-100 connects to E Series MIO devices (NI 6025E, NI 6031E, NI 6033E, and NI 6071E), DIO devices (PCI-DIO-96, NI 6508, NI 6509, NI 6511, NI 6512, NI 6513, NI 6514, NI 6515, NI 6527, and NI 6528), TIO Series devices (NI 6624), or other products with a 100-pin 0.050 series shielded D-type I/O connector.

  • Page 2: What You Need To Get Started

    Resistors and capacitors specific to your application (optional) Attaching the Quick Reference Label A quick reference label is included in the SCB-100 100-pin shielded connector block kit to show switch configurations and define screw terminal pinouts for E Series devices. Place the label on the inside of the top cover, as shown in Figure 1.
  • Page 3 Switches S1, S2, and S3 Figure 2. SCB-100 Board Parts Locator Diagram To get started with the SCB-100, complete the following steps while referring to Figures 1 and 2. Disconnect the 100-pin cable from the SCB-100, if connected. Remove the grounding screws on either side of the top cover with a Phillips #1 screwdriver.

    Close the top cover. Reinsert the grounding screws to ensure proper shielding. 10. Connect the SCB-100 to the 100-pin connector. Using the SCB-100 with DIO/TIO Devices DIO devices, TIO Series devices, and DAQ devices without analog input functionality must use the DIO/passthrough mode.

  • Page 5: Using The Scb-100 With Mio Devices

    Using the SCB-100 with MIO Devices You can take measurements with the SCB-100 and MIO DAQ devices, such as E Series, 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.
  • Page 6 Figure 4. MIO Device Modes Switch Settings Temperature Sensor Output and Accuracy The SCB-100 temperature sensor outputs 10 mV/°C and has an accuracy of ±0.5 °C. You also can determine the temperature using the following formulas: = 100 × V + 273.15...
  • Page 7 If the MIO DAQ device is configured for differential inputs, ground-referenced signal sources connected to the SCB-100 board do not require special components added to the SCB-100 board. For detailed information on connections to ground-referenced signal sources and differential inputs, refer to the E Series User Manual.

  • Page 8: Removing The Board

    For best results, use a well-calibrated MIO DAQ device so that offsets can be ignored. Eliminate offset error by grounding one channel on the SCB-100 board and measuring the voltage. This value, the offset of the MIO DAQ device, then can be subtracted by software from all other readings.

  • Page 9: Soldering, Desoldering, And Cutting Via Traces On The Scb-100 Board

    Use a low-wattage soldering iron (20 to 30 W) when soldering to the board. To desolder on the SCB-100, vacuum-type tools work best. Use care when desoldering to avoid damaging component pads.
