INSTALLATION GUIDE AND SPECIFICATIONS
NI SCB-100
Shielded 100-Pin Connector Block for Plug-In DAQ Devices
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
section for more information.
The following illustration shows the SCB-100 components.

  • 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.
  • Page 3 Caution To avoid electrical shock, do not remove equipment covers or shields unless you are qualified to do so. If signal wires are connected to the SCB-100, hazardous voltages may exist even when the equipment is turned off. Before removing the cover, disconnect the AC power or any live circuit from the connector block.
  • Page 4 9. Cold-Junction Compensation Temperature Sensor 5. Switches S1, S2, and S3 To get started with the SCB-100, complete the following steps. 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.

  • Page 6 Refer to your device documentation for device signal information. 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.

  • Page 10 Differential Inputs 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 about connections to ground-referenced signal sources and differential inputs, refer to your device documentation.

    +5 V, a value much larger than any legitimate thermocouple voltage. Sources of Error When making thermocouple measurements with the SCB-100 and a MIO DAQ device, the possible sources of error are compensation, linearization, measurement, and thermocouple wire errors.

  • Page 12: Removing The 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.
