DUT
EX10SC is supplied with sixteen connectors (VTI P/N 27-0400-004) for connecting to the device
under test (DUT). This allows the user to connect all field wiring before connecting the DUT to the
EX10SC input channels. Each input channel on the EX10S is labeled
-EXC , +EXC , -SNS , and
+SNS .

ONNECTOR
Since the 8B modules require only power and no control, no analog integration with the EX10xxA
is required. The 0 V to 5 V and +5 V to -5 V output modules were selected to match the front panel
capabilities of the EX1000A, EX1016A, and EX1032A. No hardware modifications to the
EX10xxA family of products should be required, however software driver modifications to support
additional signal types may. Because of the modular nature of the 8B modules, other modules may
be added if the business case dictates this.
For most 8B modules, calibration is not required. For the thermocouple type modules, the user can
compensate for error at the 0 °C reading by doing the following:
1) Using a thermocouple calibrator, connect the leads to connect to the +SNS and -SNS leads
inputs of the EX10SC.
2) Set the calibrator to 0 °C and determine the temperature.
3)
Enter the module’s offset, in °C, the application software (such as EXLab).
