Figure 1-3. SCC-AIXX Signal Connections

The inputs are designed in a floating (nonreferenced) single-ended

configuration. If the measured signals are floating, connect the negative

input pins, 1 and 3, to AISENSE on the SC-2345 terminal block through

a10kΩ to 100 kΩ resistor. Figure 1-4 shows a floating signal connection

on one channel of the SCC-AIXX.
