4.4.2.2 Differential current input
The WI-I/O-EX-1-S-12 can be configured to measure differential current. The differential
pairs are: AIN1-AIN2, AIN3-AIN4, AIN5-AIN6, AIN7-AIN8. To use this configuration,
choose the differential current input page, as shown in Figure 4-8.
Remove the access panel from the front of the WI-I/O-EX-1-S-12 case to
gain access to the dip switches. Replace the access panel after setting the
switches.
Set the switches according to the picture shown. The unit should be orientated with the
20-way connector towards you.
Figure 4-8: Setup page for differential current configuration.
Once the dip switches on the unit are set, tick the checkbox on the form, and click Save
configuration. Check the WI-I/O-EX Detected panel to ensure that the analog mode has
been updated (to Current, differential).
Clicking Read from WI-I/O-EX will read the scales out of the unit (if any) and display
them in the scales grid. Note that the dip switches should be set correctly for this result to
be relevant.
