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:
VOutTotal = VOUT1 + VOUT2
where
VOutTotal is the total output voltage from both SCC-AO10 modules
VOUT1 is the voltage across terminals 1 and 3 of the SCC-AO10 module in socket J17
VOUT2 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.
