SCC-AO10 Isolated Analog Output Module User Guide
Figure 3.
Connecting Two SCC-AO10 Modules in Series
The SC-2345/2350 routes the E/M Series DAQ device analog output
channels AO 0 and AO 1 to the SCC-AO10 modules, and the resulting
maximum output voltage range is ±20 V. Refer to Figure 3 and use the
following formula to calculate the total output voltage from both
SCC-AO10 modules:
where
V
OutTotal
is the total output voltage from both SCC-AO10 modules
V
OUT1
is the voltage across terminals 1 and 3 of the SCC-AO10
module in socket J17
V
OUT2
is the voltage across terminals 1 and 3 of the SCC-AO10
module in socket J18
For information about how to configure the SCC-AO10 module with
NI-DAQmx, refer to the
SCC Quick Start Guide
