Analog Output Connection
The PCI-1718HDU/HGU provides one D/A output channel. You can use
the internal precision -5 V or -10 V reference to generate 0 to +5 V or 0 to
+10 V D/A output. Use an external reference for other D/A output ranges.
The maximum reference input voltage is ±10 V and maximum output
scaling is ±10 V. Loading current for D/A outputs should not exceed 5
mA.
Connector CN3 provides D/A signals. Important D/A signal connections
such as input reference, D/A outputs and analog ground appear below:
