Note
The input and output channels of the
[c]FP-AIO-600 are
not
electrically isolated from
each other.
Figure 4 shows the input circuitry on a single input channel.

Voltage Inputs
The input ranges for voltage signals are
5,
10,
15,
30, 0–5,
0–10, 0–15, and 0–30 V. FieldPoint software accounts for the
20% overranging feature and shows the ranges accordingly.
Figure 5 shows how to connect a voltage source without an
external power supply to one input channel of the [c]FP-AIO-600.
