Input Modes
Single Ended
The PowerDAQ boards operate with either a single-ended or a
differential input configuration. Single-ended inputs allow up to 64
channels and share a common low side, which is the analog ground.
Single ended inputs are shown diagrammatically in figure 12.
See Table
5 for complete wiring instructions.
Note Unused channels should be shorted to ground using a 0
to 1KOhm resistor.
