3.3.3.5 Analog Signals to NI 9215 Analog Input Module
The DI Driver System supports an optional NI 9215 four-channel analog input module. The analog inputs are
sampled at an interval of 15 milliseconds. The analog inputs are filtered and converted to engineering units via the
Analog Input Setup window . The engineering values can be used as inputs to a variety of functions throughout the DI
Driver System, such as lookup tables and rail pressure control.
The analog input channels are capable of directly measuring differ/- 10V signals. Therefore, each channel
has a positive and negative screw terminal connection. A COM terminal is provided as a common mode reference
for all four (4) channels. Refer to the NI 9215 Operating Instructions and Specifications for detailed connection
diagrams and specifications.
