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

OutTotal

is the total output voltage from both SCC-AO10 modules

OUT1

is the voltage across terminals 1 and 3 of the SCC-AO10

module in socket J17

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.
