3.3.2 Analog Input Connections

PCI-1718HDU/HGU supports either 16 single-ended or 8 differential analog inputs. Switch SW2 selects the input channel configuration.

Single-ended Channel Connections

Single-ended connections use only one signal wire per channel. The volt- age on the line references to the common ground on the card. A signal source without a local ground is called a "floating" source. It is fairly sim- ple to connect a single ended channel to a floating signal source. A stan- dard wiring diagram looks like this:

Differential Channel Connections

Differential input connections use two signal wires per channel. The card measures only the voltage difference between these two wires, the HI wire and the LOW wire. If the signal source has no connection to ground, it is called a "floating" source. A connection must exist between LOW and ground to define a common reference point for floating signal sources. To measure a floating sources connect the input channels as shown below:
