Each screw terminal is labeled by pin number <1..4>. Pins 1 and 2 form
a differential channel routed to E Series DAQ device channel
X
+
8, and
pins 3 and 4 form a second differential channel routed to E Series DAQ
device channel
X
. The value of
X
is determined by the number of the
SC-2345 socket where you plug in the module, J(
X
+
1) or J(
X
+
9).
The signal source can be floating or ground-referenced. Floating signal
sources do not require bias resistors to ground with the SCC-A10. Figure 1
shows the SCC-A10 signal connections.
